Preface

Purpose of This Guide
This manual describes the use of DCL (Digital Command Language),
System Utility Programs, and general programming information on
RSTSIE.

Terms Used in This Guide
The following terms are used throughout this guide:
Command Line
The part of a command string you type on one line on your terminal.
Command String
A complete command, including the command name, parameters, and
switches or qualifiers (if any).
Default
A built-in value that the system assumes when you do not supply a
particular value. For example, when you do not supply a device name
in a file specification, the system assumes the public disk structure.

Parameter

Part of a command string that specifies what the command is acting
on. For example, the COPY command acts on files, so its parameters
are file specifications.
Qualifier

In DCL, part of a command string that modifies the command's action
in some way. For example, the PRINT command's /COPIES qualifier
lets you print several copies of a file. All qualifiers start with a slash
(I).

Switch

A synonym for qualifier; that is, part of a command string that modifies the command's action in some way. For example, using the IDE
switch in a PIP command causes PIP to delete the specified file. Like
qualifiers, all switches start with a slash (I).
This guide uses the term switch instead of qualifier when describing
system utility programs and command environments other than DeL.

xvi

Conventions
[ ]

Indicates an optional part of a command. This does not apply to
[p,pn] where the brackets ([ ]) are part of the required command
syntax.

( )

Indicates a required choice of one item among two or more
possibilities.
Indicates a choice of one item among two or more possibilities.
Indicates that you can repeat the preceding item in the command
format.

color

Indicates examples.
Indicates that you can use a DCL qualifier over the DECnet
computer network (if your system has DECnetlE).

Ctr]Jx

Represents the Ctrl key and another character, represented here
by x. For example, enter CtrllU by holding down the Ctrl key and
pressing the key labeled U. RSTS echoes or displays the character
at your terminal as "U.

Summary of Technical Changes for RSTS/E V10.0
RSTSIE V10.O is a major release of the RSTSIE PDP-ll operating
system. This manual describes the following new features:
•
•
•
•

Extended logicals
Host initiated (Outbound) LAT
Command line editing and recall
Operator/Message Services (OMS)

System Information
This

system information. Table 1-1 lists the RSTS/E

Key

Function

CtrliA or F'14

from overstrike
mode to insert
mode, or vice versa, while editing a command line.
Effective only unt.il a delimiter is entered, then the
mode reverts back to the terminal setting.

CtrllB or Up Arrow

Recalls the previous command typed by the user
at the current command leveL When CtrllB or Up
Arrow is entered, t.he current line, if any, is erased
and the next previous command from the recall
buffer is put in its place. The cursor is positioned
at the end of the recalled command, regardless of
the position of the cursor previous to the recalL

CtrllC

Halts execution of the current command or program
and usually returns control to the job keyboard
monitor. (In some programs, CtrllC may return you
to the program's command level.) CtrllC echoes on
the terminal as AC. You can lose data with CtrllC
because it causes an immediate halt.

CtrllD or Left Arrow

Moves the cursor to the left or backwards one
character position in the command line. If the
cursor is already at the beginning of the command
line, the key is ignored.

System Information

1-1

Table 1-1 (Cont):

1-2

Control Characters and Terminal Keys

Key

Function

CtrllF or Right Arrow

Moves the cursor to the right or forward one character position in the command line. If the cursor is
already at the end of t.he command line, the key is
ignored.

CtrllH, BACKSPACE, or
F12

Moves the cursor to the beginning of the command
line. If the cursor is already at the beginning of the
command line, t.he key is ignored.

Ct.rllE

Moves the cursor to the end of the command line.
If the cursor is already at the end of t.he command
line, the key is ignored.

CtrllI or TAB

Moves the cursor to the next tab stop on the t.erminalline. By default, w.b stops are eight spaces
apart (see the SET TERMINAUTAB command).

Ct.rIlJ, LINE FEED, or
F13

On terminals that do not support line editing, ends
the current line. LINE FEED moves the cursor
to the next line but does not return the cursor to
the left side of the screen. On terminals that do
support line editing, deletes the word to the left of
the cursor.

Ct.rlJL or FORM FEED

Sends a typed line to the system for processing
and skips four lines on a video terminal. FORM
FEED and CtrlJL advance the paper to the top of
the next page on hardcopy terminals (see the SET
TERMINAIJFORM_FEED command).

Ct.rllN or Down Arrow

Performs a function similar to CtrllB or Up Arrow
except. it moves forward in the recall list, obtaining
the next command entered. Requesting a forward
recall when at the most recent entered command
of the recall buffer results in erasing the cunent
command line on the screen and no line is recalled.

Ct.rIlO

Stops and rest.arts terminal output while a program
is running. CtrllO does not affect program execution; however, the syst.em discards all terminal
output the program produces between the t.ime you
stop output and restart it again. CtrlJO echoes on
the terminal as "0.

System Information

Table 1-1 (Cont.):

Control Characters and Terminal Keys

Key

Function

CtrllQ

Resumes terminal output suspended by CtrllS
while a program is running. You can use CtrllQ
only if the DCL TI'SYNC (or STALL) characteristic
is set for the terminal.

CtrllR

Redisplays all characters you typed since the
last time you terminated a line, as well as any
characters you typed ahead that the system has not
yet processed.

CtrllS

Suspends terminal output while a program is running. You can use CtrllS only if the DCL TI'SYNC
(or STALL) characteristic is set for the terminal.
When you use CtrllS, the system saves all terminal output that the program produces instead of
discarding it (as it does when you use CtrllO).

CtrllT

Displays a one-line status report for your job. The
report includes your job number, keyboard number,
job state, current run-time system, and other
information.

CtrllU

Erases all characters from the beginning of the line
to the cursor. The remaining characters are shifted
to the beginning of the command line. CtrllU erases
characters from the screen on terminals which
support line editing. On multiline commands,
deletes only the portion of the command from the
cursor to the left margin.

CtrllX

Deletes all type-ahead including the current terminalline. CtrllX echoes as AX and moves the cursor
to the next line.

CtrllZ

Exits most RSTS/E system programs. CtrllZ also
signals the end of a terminal input file.

Ctrll[, ESCAPE, or
ALTMODE

Sends a typed line to the system for processing
or starts an escape sequence if the terminal is set
/ESCAPE_SEQUENCE. ESCAPE, ALTMODE, and

Files
This section provides information on the file specification format, file
types, file specification switches, and file protection codes.

File Specification
A file specification is the full name and location of a file. It has the
format:
node::device:[p,pn]filename. typ/switches

1-4

System Information

where:
node::

Specifies a node name on the DECnet network. The default
node is your system. You can specify a node name only
in certain DCL and DECnetiE commands. You use node
names only if your system is part of a DECnet network.

device:

Specifies a physical or logical device name. The default
device is the public disk structure.

[p,pn]

Specifies the directory on the device, identified by its
project-programmer number (PPN). The default is your
current account. You can include a dollar sign ($) in place
of a PPN to indicate directory [1,2], which is the system
library. You can include a percent sign (%) in place of a
PPN to indicate directory [1,4]. You can include an ampersand (&) in place of a PPN to indicate directory [1,5]. You
can include a pound sign (#) in place of a PPN to indicate
directory [your project number,O].

filename

Specifies a one- to six-character file name.

typ

Specifies a one- to three-character file type. The default file
type depends 011 the command or program you are using.

/switches

Specifies one or more RSTSIE file specification switches:
!PROTECTION, /CLUSTERSIZE, IFILESIZE, !POSITION,
/RONLY, or /MODE. These switches specify the file protection code, cluster size, and other values.
You cannot use RSTSIE file specification switches in DCL
except where specified as a valid qualifier in the command
description. Instead, you use DCL commands and qualifiers
to set these values. Note that /MODE and !POSITION
switches have no DCL equivalent.

The next three sections provide more detail on file types, file specification switches, and file protection codes. Table 1-2 lists RSTSIE file
types and their meanings.

File Specification Switches
This section lists the RSTS/E file specification switches.
ICLUSTERSIZE

Specifies the cluster size for a disk file. A cluster is one or more
contiguous disk blocks that the system treats as a unit when it creates
or extends a file. Using a large cluster size for a large file speeds access
to the data.
You can specify a cluster size of 1, 2, 4, 8, 16, 32, 64, 128, or 256 blocks,
depending on the type of disk. The default (and minimum) value is the
disk's pack cluster size.

Format
/CL[USTERSIZE]:[-][#]n[.]
where:
Specifies a negative cluster size, which prevents an error if you
specify a cluster size less than the disk's pack cluster size.
#

Specifies that n is an octal number.

Specifies the cluster size in blocks.
Specifies that n is a decimal number. The default is decimal.

Example
/CL:-8

Assigns a cluster size of 8 or the disk's pack cluster size, whichever is
larger.
IFILESIZE
ISIZE

Reserves space on disk for the file. When you create a file, use this
switch to pre-extend the file to its final size. IFILESIZE and /SIZE are
the same. When you do not pre-extend a file, system assigns a size of 0
blocks when it creates the file and extends the file as data is written to
it.

1-8 System Information

Format
IFI[LESIZE]:[#]n[.] or /SI[ZE]:[#]n[.]
where:
#

Specifies that n is an octal number.

Specifies the number of blocks to pre-extend the file.
Specifies that n is a decimal number. The default is decimal.

Example
/FI:3000

Pre-extends a disk file to 3000 blocks.

IMODE
Lets you pass up to 15 bits of information to a device driver when
you open a file. The meaning of the bits differs for each device and
determines the read/write mode for data transfers.

Format
/MO[DE]:[#]n[.]
where:
#

Specifies that n is an octal number.

Specifies the mode value, which can range from 0 to 32767 (decimal).
Specifies that n is a decimal number. The default is decimal.

Example
/MO: 16

Specifies a contiguous disk file.

System Information

1-9

/POSITION

Specifies the physical location of a file on disk.

Format
IPO[SITION]:n
where:
n specifies the device cluster number (in decimal) at which to place the
first block of the file. Valid device cluster numbers depend on the disk
size.

Example
/po: 4000

Causes the system to locate the disk file starting at device cluster
number 4000.
/PROTECTION

Assigns a protection code to the file. The default protection code is 60.

Format
IPR[OTECTION]:[#]n[.]
where:
#

Specifies that n is an octal number.
Specifies the protection code.
Specifies that n is a decimal number. The default is decimal.

Example
/PR : 40

Specifies a protection code of 40.
/RONLY

Sets read-only mode for a disk file. IRONLY is the same as
IMODE:8192 for disk files.

Format
IRO[NLY]

1-10

System Information

File Protection Codes
You assign protection codes to files in all RSTS/E command environments except DCL by using the !PROTECTION switch. In DCL, you
assign protection codes to files using the SET PROTECTION command
or the !PROTECTION qualifier in several DCL commands. Table 1-3
and Table 1--4 list RSTS/E protection codes and their meanings.
Table 1-3:

128

A protected data file; overwritten with zeros when deleted

When you add individual codes to executable protection code 64, the
system interprets these codes differently from those previously listed.

System Information

1-11

To detennine the protection code you assign to a file, add up the
individual code numbers for the types of protection you want. For
example, the usual system default <60> protects against reading,
writing, and deleting by all users except its owner, because it is the
sum of 4, 8, 16, and 32.

Table 1-5 lists some common protection codes and their meanings.

32+8

Protection against writing by anyone except
the owner, but is readable by everyone.
No protection (any user can read, write, and
delete).

Device Names
Each device on a RSTSIE system has a physical device name, also
called a device designator or device specification.
A physical device name consists of two or three letters, an optional
unit number, and a colon (:). For example, "KEO:" is a "keyboard,"
or terminal, with the unit number O. Other terminals on your system
have similar device names assigned to them, such as "KE7:" or "KE35:".
Three letter names are valid for keyboards only (see Table 1-6).
If you do not specify a physical device name, the system assumes the
public disk structure. For non-file-structured devices (line printer, and
so forth), you need only specify the physical device name; the system
ignores any file name, file type, or directory that you specify.

If you do not specify a unit number, the defaults are:
Disk - Public structure
Tape - Unit 0
Keyboard - Yours
Line printer - Unit 0
Flexible diskette - Unit 0
Table 1-6 lists RSTSIE device designators.

If your system has only TSll, TU80, or TSV05 tape units,
MS: and MT: are synonyms. If your system has only
TEI6, TU16, TU45, or TU77 tape units, MM: and MT: are
synonyms. If your system has only TK50, TU81, or TU81E
tape units, MU: and MT: are synonyms. On systems that
have the CDll card reader, CR: is a synonym for CD:.

Logical Names
You can assign a logical name to a physical device name, a directory,
or a device/directory combination. A logical name consists of up to 15
alphanumeric characters followed by a colon (:). Both user and system
logical names allow the the underscore C) character. However, the
dollar sign ($) character is only allowed in the system logical names.
(
\

Logical names provide a convenient way to refer to devices and directories that you use often. Logical names are also useful in programs
and batch control files because they make them independent of physical
locations of files and devices. For example, when you use a physical
device name in a program, the program works correctly only if the
device you refer to is mounted on the drive you specify. But when you
use a logical name, you can mount the device on any free drive and
assign the logical name to the device before running the program.
Using the ASSIGN command, you can assign a logical name in any
RSTSIE command environment. The command syntax is:
ASSIGN dev:[[p,pn]] logical-name[:]
In DCL, you can include a colon at the end of the logical name. In
other RSTSIE command environments, such as BASIC-PLUS, you
cannot include the colon.
The following command assigns the logical name INDEX: to tape drive
MMO:.
ASSIGN MMO: INDEX

Any logical name you assign applies only to your job. The logical name
stays in effect until you deassign it with the DEASSIGN command or
log out.

Then discard this sheet.

Chapter 2

DCl Commands
This chapter describes how to enter DeL commands. It provides
information on each DeL command such as privileges required and
command qualifiers.

Rules for Entering DCl Commands
This section describes the rules for entering DeL commands.

Uppercase and Lowercase Letters
You can use any combination of uppercase and lowercase letters in DeL
commands.

Numbers
DeL treats all numbers as decimal integers.

Spaces and Tabs
You must enter at least one space or tab between the command name
and the first parameter and at least one space between additional
parameters. You can use multiple spaces and tabs in all cases where
you can use a single space or tab. For example:
COpy DAY.DAT

NIGHT. OAT

DCl Commands

2-1

DCL ignores spaces and tabs at the beginning and end of a command
string; around commas, plus signs, and equal signs; and around colons
that delimit qualifier values. You cannot use spaces and tabs in file
specifications, dates and times, keywords, and numbers.

Qualifiers
You type a qualifier after the command name but before pressing
RETURN. You must precede each qualifier with a slash (/). You can
include any number of spaces or tabs before or after the slash. For
example:
PRINT STATUS . RPT

/COPIES=5

Entering Qualifier Arguments
Many qualifiers have arguments, which can be keywords, file specifications, character strings, or numbers. You must separate a qualifier and
its argument with either an equal sign (=) or a colon (:). For example:
SET TERMINAL/WIDTH=132
SET TERMINAL/WIDTH : 132

Command Line Labels
Command line labels identify lines in a command procedure to which
control passes when a GOTO or GOSUB command executes. Labels
can be 1 to 255 characters long using the characters A-Z, 0-9, $,
and _. Labels must appear as the first item on a command line, must
be preceded by a dollar sign ($), and must be followed by a colon (:).
For example:
$LABEL1:

You cannot use labels that begin with a dollar sign ($), or include
embedded spaces or tabs. You can specify only one label on a command
line. You cannot use a label name more than once in a command
procedure.

2-2

DCL Commands

Abbreviating Commands
You can abbreviate command names, command keyword parameters,
qualifiers, and qualifier keyword values:
•

You can always abbreviate command names, parameters, qualifiers,
and qualifier arguments to the first four characters, excluding
slashes and underscores. You can further abbreviate to the first
two or three characters as long as the abbreviation is unique within
DeL. For example:
PR STATUS.RPT/FO=NORMAL

•

Some qualifiers permit a negated form . For example, INOJOURNAL
is the negated form of the IJOURNAL qualifier. When applying the
minimum four-character rule, do not include the NO prefix as two
of the four characters. For example:
EDIT/NOJOUR FILE . OAT

Continuing Commands on More Than One line
The entire specification of a command is called the command string,
which can be one or more physical command lines . You can enter up to
132 characters on each physical line. When you use multiple physical
command lines to continue a command string, type a hyphen (-) as the
last character on each line before pressing RETURN. You can use as
many physical lines as you want as long as the complete command
string does not exceed 255 characters.
For example:
PRINT STATUS.RPT/COPIES=5,continue: CHKBK.B2S/COPIES=2,Continue : CHAP3.TXT/COPIES=10

If you include a comment on the command line, the hyphen must be
the last nonblank character before the comment. For example:
PRINT STATUS.RPT/COPIES=2-!THIS IS A DRILL REPORT

When you recall a command that has been entered on more than one
line, the entire command is displayed on one line with the hyphens
removed.

DCl Commands

2-3

Entering File Specification Lists
When you enter more than one file specification, separate them with
commas C,) or plus signs C+). Any number of spaces or tabs can precede
and follow the commas or plus signs. For example:
DELETE JUNK . TXT,OLDPRG . B2S
APPEND PART1.TXT +PART2 . TXT+

PART3 . TXT WHOLE . TXT

Absolute Date Formats
You can specify any date from 1-JAN-70 to 31-DEC-99. Use one of the
following formats:
•

•

The alphanumeric format dd-mmm-yy. In this format, you specify
June 13, 1989 as 13-JUN-89. You do not have to include leading
zeros. You can also specify four digits for the year. When you omit
the year, the current year is the default.
The numeric format yy.mm.dd. In this format, you specify April 9,
1989 as 89.4.9. You do not have to include leading zeros. You can
also specify four digits for the year.
The keywords TODAY, TOMORROW, or YESTERDAY. The current
system date determines the values for these keywords.

Absolute Time Formats
Use one of the following formats:
•

The 24-hour format hh:mm. In this format, hh is the hour in the
range 0 to 24 and mm is the minute in the range 0 to 59. The
minute is optional.
00:00 is midnight, and is considered the beginning of the specified
date.
12:00 is noon. 24:00 is midnight, and is considered the end of the
specified date.

2-4

DCl Commands

•

The AMlPM format hh:mmAM, hh:mmPM. or 12:00M. In this
format, hh is the hour in the range 1 to 12, mm is the minute in
the range 0 to 59, and M stands for meridian (noon). Do not include
a space between the minute and AM, PM, or M. Use 12:00AM to
specify midnight.

Combining Absolute Dates and Times
To specify both date and time, use date:time, where date and time are

any of the absolute date and time formats previously described. For
example:
16-DEC-89:11:00AM
TOMORROW:l:00AM

If you specify only a time, the date default is TODAY. If you specify only
a date when using the IAFTER qualifier, the time default is 11:59PM.
That is, the job is processed at the end of the specified day.

Relative Dates and Times
Use one of the following formats:
•

To change the date using relative dates, use the format +nD[AYS]

or -nD[AYS]. For example:

•

+23D, which increments the specified absolute date by 23 days. If
you do not specify an absolute date, the date default is TODAY.
To change the time in a DATE:TIME specification, use +nH[OURS]
or -nH[OURS] to change the hour. To change the minute, use
+nM[INUTES] or -nM[INUTES]. For example:
-2HOURS-20MINUTES indicates a time 2 hours and 20 minutes
from the absolute time. If you do not specify an absolute time, the
time default is the current time.

You can specify these formats in any order and in any combination.

DCl Commands

2-5

Combining Absolute and Relative Dates and Times
When you combine absolute and relative dates and times, you must
specify the absolute date and time first, immediately followed by the
relative date and time. For example:
lO-AUG-89 : 10 : 12AM- 2DAYS+3HOURS+30MINUTES

returns 8-Aug-89 at 1:42PM.

DCl Commands and Qualifiers
This section lists RSTS/E DCL commands and qualifiers.

DCl Commands

I[NO]QUEUED
Specifies the queuing characteristic of the local LAT port you are
allocating. This setting is in effect until you deallocate the device. If
IQUEUED is specified, connections initiated by this local LAT port to
a tenninal server will be placed on the server's queue if the server
supports queuing and the remote port is busy. If /NOQUEUED is
specified and the remote port is busy, connections will not be queued
and it will fail.
Use the SHOW PORT command to display the port's connection status.
If the port is set IQUEUED and the remote port is busy, a connection
status of "In Progress" and the position in the queue will be shown.
The default is the queued setting of the port when it was created or
assigned.

Chapter 3

Del Functions
This chapter provides information on DCL functions. Use DCL functions to manipulate strings or integers or return information about
a file, a job, or the system. You can use DCL functions in the same
places you use symbols, expressions, or literal values. In command
procedures, DeL functions perform operations such as:
•
..
..

Translating logical names
Manipulating strings
Determining the current processing mode of the procedure

Format of DCl Functions
A DCL function has the general format:

F$function-name([arg, ... J)
where:
F$

Indicates a DOL function.

function-name

Is the function DOL evaluates. You can truncate function
names to any unique abbreviation with a minimum of two
characters.

()

Are parentheses that enclose function arguments. You
do not need to include parentheses if the function has no
arguments.

Del Functions 3-1

arg, ...

Specifies one or more function argument.!;!, if any. Function
arguments can consist of symbols, integer expressions,
string expressions, or other DOL functions.

DeL performs automatic symbol substitution on all function arguments. Therefore, when you use a symbol name as a DeL function
argument, you should not enclose the symbol name in apostrophes.
In some cases, one or more arguments are optional. If an argument is
optional, you can exclude it from the argument list. You can also use
commas to indicate which argument you are excluding from the list.
For example, the F$PARSE function has three optional arguments . You
can specify the first argument only, as follows:
F$PARSE(ARG1)

In this example, you do not specify the second and third arguments.
You could also use commas to indicate that you are excluding the
second and third arguments. For example:
F$PARSE(ARG1,,)

To specify the first and second arguments but omit the third, you can

use either format:
F$PARSE(ARG1,ARG2)
F$PARSE(ARG1,ARG2,)

To specify the first and third arguments but omit the second, you must

use commas to separate the arguments. For example:
F$PARSE(ARG1"ARG3)

If a function accepts arguments but you omit all arguments, you can
also omit the parentheses.

Note that in some cases, specifying an argument as a NULL string or
as the integer zero is not the same as excluding the argument from an
argument list.
This section shows the format and briefly describes each of the DeL
functions. See the RSTS / E Guide to Writing Command Procedures for
complete descriptions of the DeL functions.

By default, DIRECT displays output on your terminal. Input can be
any number of disk file specifications. The disk file specification on
input can include a device, file name, file type and project/programmer
number (PPN).
If you do not specify a device, DIRECT uses the public disk structure

and denotes it by the SY: specification.
You can substitute the asterisk (*) character and the question mark (7)
character wildcards in the file name and file type fields. In addition,
you can substitute the * character in the PPN field.
You can substitute the * character for the entire file name, the entire file type, both the file name and file type, and the entire file

File attributes are system attributes or file description data that RMS11 software requires. For instance, both COBOL and BASIC-PLUS-2
use RMS-11. The User File Directory (UFD) for a given file contains
the file attributes for that file. You can list file attributes symbolically,
using the ISA, IAT, and IS switches and octally, using the lOA switch.
The symbolic file description attribute fields are:
BK
Displays if the file organization is relative or indexed; indicates the
bucket size in block.

System Utility Programs

FILCOM
FILCOM (File Compare) lets you compare two ASCII files, line by line,
and identifies differences. When you run the program, specify the files
you want to compare and any switches that direct that comparison.
Privilege Required

•
•

Read access to the files you want to compare
CreatelRename access for any output file you create

To Run the Program
RUN $FILCOM

Usage Notes

After FILCOM prompts "OUTPUT TO <KB:>?", type one of the three
responses:
•

The device designator or file specification to which FILCOM writes
the comparison data. Your terminal is the default.
If you respond with a device designator or a RETURN key, FILCOM
displays a series of additional prompts. These prompts request:
The files you want to compare.
When you specify the files to be compared, include the file type.
You can use the wildcard specifications asterisk (*) and question
mark (?) to designate the input files.
The number of successive lines in the files that constitute a
match.
As FILCOM compares lines in a file, it prints the differences
until it finds a series of lines that are identical. The number of
lines that constitute a series are determined by your answer to
this prompt. The default is three lines.
Whether FILCOM should consider BASIC-PLUS continuation
lines as part of a numbered line.
By default, FILCOM treats continuation lines as new lines.

System Utility Programs

4-7

Whether FILCOM should compare blank Jines.

•

You can also specify one or more switches in response to
FILCOM's initial prompt. These switches override the prompts
and provide an alternative way to set comparison parameters.
A single command line that contains all the information FILCOM
needs to make the file comparison:
OUTPUT TO <lill:>? output=inputl,input2,1switches
Output can be:
A complete RSTSIE file specification.
A wildcard specification (description in "Wildcards" section).
No specification. If you specify only input, FILCOM displays
output at your terminal.
The equal sign (=) is required only if you specify output. An
equal sign with no output specification causes FILCOM to
output the result of its comparison to a file on the public
structure. FILCOM creates this file in the current account with
a file name taken from the first input file and a .DIF file type.
The input files represent the two files you want FILCOM to
compare. You can describe these files with full file specifications, file names and types, or wildcards.
If you specify the full command line, FILCOM does not display

•

any other prompt and begins the file comparison. Using the
command lets you specify wildcards (*) and (?) in the file
specifications and one or more switches.
A command line that contains an indirect file name. The indirect
command file is an ASCII text file you can create with PIP or an
editor. The file must contain all of the information FILCOM needs
to make the file comparison:
output to <kb:>? @filename
In the previous command line above, the file name is an indirect
command file. The indirect command file can contain a single line
command, or it can contain multiple line answers to the FILCOM
prompts. If the command file contains answers to the FILCOM
prompts, each prompt must be answered in the four step sequence.
You cannot nest indirect command files. FILCOM processes an at
sign (@) in the command file as an assignable account specification.

4-8

System Utility Programs

Wildcards

You can specify FILCOM input files as full RSTSIE file specifications
or as wildcard characters. When you use wildcards, FILCOM bases its
search for files on the first input file specification. FILCOM output files
can contain a wildcard for either the file name or type. You cannot use
wildcards in both fields.
With wildcards, you can cause FILCOM to make multiple file comparisons based on a single command line specification. When you use this
method, FILCOM displays the differences found in each set of files in
the standard manner. Mter it finishes comparing the files, FILCOM
displays a summary of the format:
X DIFFERENCES FOUND IN Y FILES OF Z TOTAL FILES
COMPARED
Where X is the number of differences in aU files, Y is the number of
files that contain differences and Z is the number of files compared.
Switches

lAP
Directs FILCOM to open the output file for APPEND. If you omit
this switch, FILCOM deletes any existing output file of the same name
before writing differences. With the lAP switch, you can direct FILCOM
to write differences into an existing output file.
I[NO]BA
Specifies whether FILCOM considers BASIC-PLUS continuation lines
as part of a numbered program line. The default is INOBA.
I[NO]BL
Specifies whether FILCOM considers blank lines in its comparison.
The default is INOBL.
ICO[:m:n]
Converts tabs to the appropriate number of spaces and directs FILCOM
to compare characters starting in column position m and continuing for
n characters. If you include the ICOMPARE switch but do not specify m
or n, FILCOM defaults m to column position 1 and n to 72 characters.

!LI[:n]
Specifies the maximum number of lines that are allowed to differ before
FILCOM stops examining the file. If you include the !LIMIT switch but
do not specify a limit in n, the default is 60 differing lines.
System Utility Programs

4-9

/MA[:n]

Specifies the number of lines in the file that constitute a match. The
default is three.

/SU
Directs FILCOM to list the total number of differences found in the
files without listing individual lines.

System Utility Programs

For PMDUMP to be successful in formatting the dump:
•
•
•

The run-time system that controls your job must be RSX or RSXbased.
The task to be dumped must have already aborted.
You must request a postmortem dump with the /PM switch when
you link the program with the Task Builder. The /PM switch causes
the Task Builder to set an indicator in your executable program file.
This means that, if your program terminates abnormally when it is
executed, the system automatically writes the memory contents to
a disk file.

DATE$(N%)

Returns the date string corresponding to the specified calendar date
N%. To determine the value of N% given a particular day of the year
and the year, use this formula:

Programming Information

5-33

For example, the value of N% for June 14, 1989 is:
N% = (165) + (19 * 1000) = 165 + 19000 = 19165
DATE$(19165%) returns 14-Jun-89. If your system default is the
numeric date format, DATE$(19165%) returns 89.06.14.

\

For example, asswne a BASIC-PLUS program that has the following
line:
100 IF A% THEN GOTO 200

If A% equals zero then the GOTO is not executed (A% is "false"). If A%
is nonzero, A% is "true" and control passes to line 200.
NOTE

You can use non-Boolean true values, but be careful. For instance, suppose that A$ = 'ABCD' and F$ = '$NOTICE.TXT'.
Consider the following statement:
IF LEN(A$) THEN 100

Control passes to line 100 because 4% (the length of A$) is
"true". Now consider the following statement:
IF INSTR(l %, F$ ,

' .') THEN 100

Again, control passes to line 100 because F$ contains a
period (,.'), and is thus true.

Programming Information

5-45

Be careful, however, when combining non-Boolean TRUE
values (that is, true values other than -1%). For example:
IF LEN(A$) AND INSTR(O %, F$, '.') THEN 100

You might assume that if the length of A$ is true (nonzero)
and string F$ contains a period, that the combined statements are true (true and true = true). This is not necessarily
the case. If the length of A$ is 4% and the period in F$ is
in the eighth position, for example, the 4% AND 8% = 0%,
which is false. Thus, non-Boolean true AND non-Boolean
true can equal false.
Keep in mind that the logical operators evaluate all 16 bits
of a PDP-ll word. The standard Boolean values are all bits
o for false, and all bits 1 (value -1%) for true.

Integer Data
BASIC-PLUS stores integer data in binary format. Each integer uses
one PDP-ll word (16 bits). Integer values can range from -32768% to
32767%. The following diagram shows the internal integer format:
Bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
S ~ high byte ~ I+" low byte ~

Bits 0 through 14 each correspond to a positive power of 2. That is, if a
1 occurs in bit position 5, then the value for that bit is (2"5) or (32). Bit
15 stores the number's sign; 0 means the number is positive; 1 means
the number is negative. Positive integers range from 0% to 32767%
and negative integers from -1% to -32768%.

and negative integers:

Floating-Point Data
BASIC-PLUS stores floating-point data in binary format. The number
of PDP-ll words that the floating-point number uses depends on the
math package that your system has:
•

•

If your system supports a single-precision math package, then each
floating-point number uses two PDP-ll words. Single-precision
math lets you accurately represent up to six decimal digits.
If your system supports a double-precision math package, then each
floating-point number uses four PDP-ll words. Double-precision
math lets you accurately represent up to fifteen decimal digits.

Regardless of the math package that your system supports, floatingpoint numbers can range from approximately lOA-38 to approximately
lOA38.

String Data
A string is a sequence of ASCII characters treated as a unit.
Theoretically, a string can contain up to 32767 characters, but in
reality, the string is limited by the amount of available memory.
The following diagram shows how strings are stored in a PDP-11
computer. The diagram uses the string 'ABCDEFG' (the numbers to
the left and right of the diagram are hypothetical PDP-11 addresses;
the numbers inside the boxes represent the ASCII character codes for
each character in the string 'ABCDEFG').

word 10.

BASIC-PLUS Cross-Reference Program (BPCREF)
The BPCREF (BASIC·PLUS Cross Reference) program produces a
cross·reference listing of a translated BASIC-PLUS (.BAC) program.
When you enter BPCREF, you must specify the files you want processed.

5-50

Programming Information

To Run the Program
RUN $BPCREF

Format

BPCREF command? output.crf=input.bac[,input.bas][lswitches]
where:
output.crf

Is the cross-reference listing file

input.bac

Is the translated file to process

input.bas

Is the source file to include in the listing

iswitches

One or more optional qualifiers

Usage Notes

(

You do not have to specify output. If you do not specify output, do not
specify the equal sign (=). BPCREF automatically produces an output
file having the same name as the input file, but having the .CRF file
type.
BPCREF Switches

IHEL[P]
Displays information about BPCREF command formats.
INOD[ELETE]
Informs the spooling program not to delete the output files after
printing.
INOH[EADER]
Omits header lines in the output file. The resulting .CRF file is more
suitable as an input file to the FILCOM program.
IP[AGE]:nnn
Specifies nnn as the number of lines per page to print in the output
listing. The default is 60 lines per page.
IQ[UEUE]
Automatically queues the output file to the line printer. BPCREF
deletes the output file after printing unless you use the INODELETE
switch.

Programming Information

5-51

IS[OURCE]
Includes the source :file in the output :file. Use this switch when the
.BAS :file is in the same account and has the same :file name as the
.BAC file. Otherwise, specify the source :file in the BPCREF command.
IW[IDTH]:nnn
Sets the width of the cross reference listing to nnn columns per line.
The default width is 132 columns; the minimum width is 72 columns.
IGL[OW]:nnn
IGH[IGH]:nnn
Used as a pair, these switches specify a global listing. BPCREF prints
line numbers and variables referenced both inside and outside the
program boundaries indicated by the line numbers nnn. BPCREF does
print line numbers or variables referenced only inside or outside the
boundaries. The default value for IGL is 0 and the default value for
IGH is 32767.
ILL[OW]:nnn ILH[IGH]:nnn
Used as a pair, these switches specify a local listing. BPCREF prints
the line numbers and variables referenced inside the program boundaries indicated by the line numbers nnn. BPCREF does not print line
numbers or variables referenced outside the boundaries or referenced
both inside and outside the boundaries. The default value for ILL is 0
and the default value for ILH is 32767.
INO[CREF]
Omits the full cross-reference listing. Use it when you want only a
local or global listing.

SPEC% Function for Disks
The SPEC% function for disk files has the format:
VALUE%=SPEC%(FUNCTION%, BLOCK, CHANNEL%, 0%)
where:

5-54

VALUE%

Depends on the particular function code you specify in
FUNCTION%. In most cases, VALUE% is equal to the
BLOCK parameter.

FUNCTION%

Is a function code that specifies the desired operation.
During normal I/O operations, a block, or range of blocks, is
implicitly locked when you read the file with a BASIC-PLUS
GET statement. The SPEC% function allows you to convert
implicit locks to explicit locks and to release selected locked
blocks. The code specified in FUNCTION% determines the
use of SPEC%. The codes are:

Programming Information

FUNCTION% = 0%

Releases all locked blocks.

=1%

Releases the current implicit lock.

FUNCTION% = 2%

Converts the current implicit lock
to an explicit lock.

FUNCTION% = 3%

Releases the explicitly locked
block specified in the BLOCK
parameter. If BLOCK is 0, all explicitly locked blocks are released.
However, implicitly locked blocks
remain locked.

FUNCTION% = 4%

Converts an implicit lock to an
explicit lock and release the
implicit lock.

FUNCTION%

BLOCK

Specifies the starting block number for releasing an explicit
lock. Note that BLOCK must be a floating-point number.

CHANNEL%

Is the I/O channel on which the operation is to be performed.

codes are:
Returns the density of the curFUNCTION% = 0%
rently mounted diskette in t.he
format:
DENSITY% = VALUE% AND
255%
IfDENSITY%=l%, the diskette is
single-density; if DENSITY%=2%,
the diskette is double-density.
Note that PARAMETER must
also be O.
FUNCTION% = 1%

Causes the diskette driver to
recompute density. If the diskette
has been changed in the drive
without closing and reopening
the 110 channel, issue this code
prior to any 110 operation on
the diskette. This function also
returns the computed density as
described in FUNCTION%=O%.
Note that PARAMETER must be

O.
FUNCTION% = 2%

Reformats the current diskette
to the density in PARAMETER.
PARAMETER equals 1 for singledensity and 2 for double-density.
Note that this operation is allowed only on RX02 drives and
that any data on the diskette
before the operation is lost.

Syntax and ParSing
The following sections provide infonnation on Command Syntax and
Parsing.

Command Syntax
The following lines show the proper syntax for a CCL command caned
COMMAND. (Note that '<anything>' represents characters that the
CCL parser does not process):
COM[MAND] [<switch(es»] [/<anything>]
Programming Information

5-91

COM[MAND] [<switch(es»] [<space><anything>]
The command line may contain two switches: lSI and IDET.
The format for the lSI switch is:
[<space> ]/SI[ZE]:[ +][#]<digits>[.]
where:
lSI

Denotes the size in K words to which the program must expand.
Tenninates the ISIZE switch.

Designates an increment in size over the program's usual size.
Without the plus sign, the digit's value is the total size in K
words to which the program should expand.

Indicates the digit's value is given in octal. The default is
decimal.

Is the value for size, in K words. Size can be neither less than
1 nor greater than 32 (decimal).
Explicitly indicates a decimal value for digits.

The format for the IDET switch is:
[<space>]IDET[ACH]
Where IDET indicates that the program is to run detached from the
job's console terminal.

Command Parsing
The run-time system passes the command line to the eeL parser.
When the CeL parser receives a command string, it:
1. Translates the string
2. Checks the string for a valid CCL command
3. Writes the fully expanded CCL command into core common, and
ensures that it is delimited by a space
4. Checks the remaining string for both of the valid CCL switches
5. Writes the remaining line (excluding CCL switches) to core common
6. Sets up the CCL program to run
7. Sets a flag from data in the CCL command definition block
5-92

Programming Information

Passes control back to the program's run-time system, wruch,
in turn, runs the program (at the appropriate line number for
BASIC-PLUS programs)

The BASIC-PLUS run-time system then:

1. Sets the STATUS variable
2. Checks the line number at which the program is to be entered
3. Checks whether the program is to be detached
BASIC-PLUS sets the STATUS variable according to the rules in
Table 5-24.
Table 5-24:

Bit

BPSTATUS Variable Bits
Test
Meaning

0-7

(STATUS AND 255%)

8-12

If bit 13 is 0, this byte must be
O. If bit 13 is 1, this byte is the
size value n (in decimal) passed
in the /SIZE:n switch or is -n to
indicate that the size value was
passed in the /SIZE:+n switch (the
plus character preceded the size
value). (To determine whether the
size value is negative, check the most
significant bit by the (STATUS AND
128%) test.)

Reserved for future use.

(STATUS AND 8192%)

If the /SIZE:n switch was specified,
this bit is 1.

(STATUS AND 16384%)

If the IDET switch was specified, this
bit is 1.

(STATUS < 0%)

This bit is always 1 (the value of
STATUS is always negative for a
CCL entry.O

OPSER and Obsolete System Utility
Programs
This appendix describes the OPSER and obsolete system programs.

(

BATCH (OPSER-based)
BATCH lets you process work that can be run in your absence. You run
a batch job by fir st putting batch commands into a control file that you
create.
Privileg e Required

•
•

Read access to the files you are submitting
Write access to use !DELETE

To Run the Program
RUN $QUE

Format

#Q BA:BATJOB.LOG=FILE 1. CMD,FILE2. CTL
$BASIC Command

Calls a BASIC compiler to compile a source program.
Format

$BASIC[lswitches][specification field][Iswitch][specification fields]

OPSER and Obsolete System Utility Programs

A-1

Switches

!BPI
Uses the BASIC-PLUS compiler. The default is /BPI. The default file
type is .BAS.
/BP2
Uses the BASIC-PLUS-2 compiler. The default is /BPI. The default file
type is .B2S.
/EXECUTE
Creates an executable file. You can choose the file type according to the
following rules:
..

If you use BASIC-PLUS, give the file a .BAC file type.

•

If you use BASIC-PLUS-2, give the file a .TSK file type.

/NOEXECUTE
Creates a temporary executable file, if one is needed, and deletes the
file when $BASIC processing completes.
!LIST
Produces the listing file filename .LST. The default is lNOLIST.
/NOLIST
Does not produce a listing file. The default is /NOLIST.

/MAP
Creates the Task Builder map file filename .MAP. This switch causes
BASIC-PLUS-2 to run; it also causes a Task Build operation. The
default is /NOMAP.
/NOMAP
Does not create a map file. This switch causes BASIC-PLUS-2 to run.
The default is INOMAP.
lOBJECT
Creates the object file filename .OBJ. The IOBJECT switch causes the
BASIC-PLUS-2 compiler to run; it also causes a Task Build operation.
INOOBJECT
Creates the object file filename .TMP. This switch causes the BASICPLUS-2 compiler to run.

A-2

OPSER and Obsolete System Utility Programs

/RUN
Executes a previously compiled and task built program. If you
use /RUN, you can indicate only one file specification and only one
switch: /EXECUTE.
/NORUN
Performs the compiled and task build procedure, but does not execute
the final file.
$COPY Command

Copies files.
Format

$COPY filel/output file2/input
Usage Notes

You cannot use an asterisk (*) in file specifications with this command.
Switches

/INPUT
Copies files.
/OUTPUT
Creates new files.
$CREATE Command

Creates an ASCII file in the specification field.
Format

$CREATE file
Usage Notes

The ASCII file you create must follow the $CREATE command. You
must type $EOD as the last line of the ASCII file; otherwise, you
receive an error message. When it encounters a dollar sign ($) in the
first column of a line, $CREATE terminates. Therefore, do not specify
any commands preceding the ASCII file you create.

OPSER and Obsolete System Utility Programs

A-3

$DATA Command

Enters data to a program that is compiled and run by one of the
language commands (for example, $BASIC). $DATA also makes sure
that the program runs (unless you specify the INORUN switch).
Format

$DATA
Usage Notes

$DATA is typed without specification fields or switches.
$DELETE Command

Deletes the files you specify.
Format

$DELETE file1.typ[file2.typ ... ]
Usage Notes

You must include a file name and file type in the specification field.
You cannot use an asterisk (*) in either the file name or file type field.
$DELETE has no switches.
$DIRECTORY Command

Lists files in an account you specify.
Format

$DIRECTORY [specification field]
Usage Notes

You can include file specifications in the specification field. If you do
not include any file specifications, $DIRECTORY lists the contents of
the current account in the batch log file. You can use an asterisk (*) in
either the file name or file type fields.

A-4

OPSER and Obsolete System Utility Programs

Switches

/DIRECTORY
Creates a directory listing in a disk file instead of the batch log device.

/INPUT
Designates which files are to be listed.
$DISMOUNT Command

Cancels the logical to physical device assignment made by the
$MOUNT command.
Format

$DISMOUNT [Iswitch] logical name:
Switch

!WAIT
Holds the job until a response (as with the $MESSAGE command) is
received from the operator.
$EOD Command

Marks the end of data records included in data you input after commands such as $BASIC, $CREATE, $DATA, and $RUN.
Format

$EOD
$EOJ Command

Marks the end of a job. The $EOJ command dismounts all devices
mounted by the job and prints an appropriate message to the operator
that the logical device should be dismounted.
Format

$EOJ
Usage Notes

When BATCH reaches the end of a control file (or another $JOB
control statement) while processing a control file, the $EOJ command
is implied.

A-5

$FORTRAN Command

Calls the FORTRAN-IV compiler to compile a source program and
generate an object program.
Format

$FORTRAN[!switches][specifica tion field]
Switches

/LIBRARY
Indicates a library file to link with the FORTRAN program.
/LIST
Produces the listing file filename .LST. The default is INOLIST.
INOLIST
Does not produce a listing file. The default is INOLIST.
/MAP
Creates the map file filename .MAP. The default is INOMAP.
INOMAP
Does not create a map file. The default is INOMAP.
IOBJECT
Creates the compiled file filename .OBJ. The default is INOOBJECT.

INOOBJECT
Does not create an object file. The default is INOOBJECT.
!RUN
Executes the previously compiled file. You must specify an object file.
INORUN
Compiles the source program, but does not execute the object file.
$JOB Command

Marks the beginning of a batch job.
Format

$JOB [/switches] [n,m]

A-6

OPSER and Obsolete System Utility Programs

Switches

fCCL
Uses the system's interactive Concise Command Language (CCL).
If you specify this switch, any of the system commands that do not
conflict with existing BATCH commands can follow the dollar sign ($)
character.
fCPU=nn
Assigns a CPU time limit to the job. The value of nn is a decimal
number that is interpreted as seconds. If you specify fCPU without
!LIMIT, no elapsed time limit is enforced, and the only time limit is on
CPU time. If you specify fCPU and !LIMIT, both limits are enforced.
INOCPU
Gives the job an unlimited amount of CPU time to complete.
/DCL
Disables all current BATCH commands that conflict with DCL commands and allows them to be processed by DCL. The job is spawned
under the DCL run-time system. If you do not include this switch, the
job is spawned under the RTll run-time system.
IERROR=[operand]
Specifies the level of error the batch processor accepts without terminating the job. The level is indicated by [operand], which can be
FATAL, WARNING, or NONE. If FATAL, all errors are accepted until
completion. If WARNING, a fatal error terminates the job, but warning errors are accepted. If NONE, any error terminates the job. The
default error level is determined at system start-up.
!LIMIT=nn
Assigns an elapsed time limit to the job. The value of nn is a decimal
number that is interpreted as minutes. Note that the elapsed time
taken to execute a job depends heavily on overall system loading.
INOLIMIT
Gives the job an unlimited amount of elapsed time to complete. If you
do not specify !LIMIT=nn or INOLIMIT, the job is given ten minutes
elapsed time to complete execution before BATCH terminates it.
INAME=job
Assigns a name to the job. Job names can be one to six characters long.
This name overrides the control file name as the identifier of the job.

OPSER and Obsolete System Utility Programs

A-7

/NONAME
Indicates that no job name is defined. The system assigns a default job
name, which is the name of the control file.
IPRIORITY=n
Sets the job priority to n (or the next lowest multiple of 8) for batch
processing. If you are privileged, n can be between -120 and +127. If
you are nonprivileged, n is limited to a value between -120 and -8. The
default is -8.
IQUE
Queues the batch log file to LPO: (the default) or the device specified at
system start-up.

/NOQUE
Suppresses printing of the batch log file.
$MESSAGE Command

Logs a message on the operator services console.
Format

$MESSAGE[!switch] message-string
Switch

!WAIT
Makes the program pause to wait for operator action. This condition
stays in effect until the operator responds to the message on the
operator services console. See the RSTSIE System Manager's Guide
for information on response procedures.
$MOUNT Command

Causes a logical to physical device assignment.
Format

$MOUNT devn:Uswitch] devm:Uswitch]

A-8

OPSER and Obsolete System Utility Programs

Usage Notes
You must specify both the logical and physical devices. The physical
device refers to the physical device type. Enter the device and unit
number in the standard format (for example, MTl:). You can specify
logical device names that have one to six characters. Use the colon (:)
as the terminator for each device specification.

Physical Device Switches
IDENSITY:nn
Specifies density for magnetic tape.
IPARITY:[ODD]
[EVEN]
Specifies odd or even parity for magnetic tape.

!PHYSICAL
Identifies the device specification as the physical device. This is the
default.
NID:[string]
Identifies the volume for the operator.
!WRITE
Tells the operator to write-enable the device or volume.
/NOWRITE
Tells the operator to write-protect the volume.

logical Device Switch

!LOGICAL
Identifies the device specification as the logical device name. This
specification must correspond to the pack-id label for RSTSIE disks.
$PRINT Command

Prints the contents of files on the line printer.

Format
$PRINT file1.typ/switches [file2.typ ... J

OPSER and Obsolete System Utility Programs

A-9

Usage Notes

You can use the switches available with the QUE system program for
all file specifications. See the QUE command for a description of the
switches. You can use an asterisk (*) in file specifications.
$RUN Command

Executes system programs.
Format

$RUN [file.typJ
Usage Notes

The file specifies the executable program. If you omit the file, the
system runs the current program.
$SORT Command

Executes the SORT-ll program that is supplied on RSTSIE systems.
See the PDP-ll SORT/MERGE User's Guide for more information on
SORT-ll.
Format

$SORT [Is witches] [output [lOUTPUT]] [input [/INPUT]] [spec/SPEC]
Usage Notes

You can abbreviate job switches to the first three letters. If you specify
more than one switch, separate them with slashes (/).
If you specify ISPECIFICATION, you cannot use the /KEYS and
!PROCESS switches in the command line. However, if you do not
use a specification file in the control statement, you must include the
/KEYS switch in the command field to control the sorting process.

You must always include the /FORMAT switch in the command field. A
file specification without a switch is used as the file to be sorted. If you
omit the file type in the file specification, the default is .SRT.

A-10

The RSTSIE RESTOR program lets you return files you backed up
before RSTSIE V9.0 (using the BACKUP program) to online use. The
RSTSIE V9.0 RESTOR utility includes the restore features previously
included in the BACKUP utility. RESTOR provides three operational
modes:
"
..
..

Restore, to rebuild Backup-created files onto a RSTSIE disk
Loadindex, to copy the primary index file from the last volume of
the Backup Set to a RSTS/E formatted disk
List, to print directory information contained in a Backup index file

Privilege Required

To run RESTOR, you need WACNT, WREAD, and WWRITE privileges.

OPSER and Obsolete System Utility Programs

A-15

To Run the Program
RUN RESTOR$:RESTOR

The dialogue begins when you run RESTOR. The first question asks
which of the three operational modes (Restore, Loadindex, or List) you
want to perform. If you choose, you may create an indirect command
file. The dialogue then asks you where to create the work file into
which it will write the directory and error information. Additional
questions ask for information on which files and accounts to transfer. When the dialogue ends, the program writes a summary of your
commands into the listing file. Table A-I, Table A-2, and Table A-3,
summaries of the Restore, Loadindex, and List dialogues, follow.
Table A-1 : RESTOR Dialogue Summary
Question

Response and Meaning

OPSER and Obsolete System Utility Programs

Table A-3 (Cont.):

LIST Dialogue Summary

Question

Response and Meaning

INDEX FILE<PRIMARY>?
File specification
Extracts the index file from the specified file and writes it to the listing file. If you
accept the default by pressing RETURN or LINE FEED, LIST requests the index
volume. It then takes the directory information from the index volume and writes
the information to the listing file.

FROM DEVICE<_MT:>?
File specification
Asked only if you accept the default in the INDEX FILE<PRlMARY> question. The
file specification response must identify the device on which the index resides. You
can accept the magnetic tape default <_MT:> by pressing RETURN or LINE FEED.
The LIST program begins a MOUNT dialogue, which asks you to mount the Backup
Set index volume and identify the target device.

File Specifications

Several questions in the dialogue require you to respond with a file
specification. The specification can include file name, account, and
dates of creation and last access. In addition, you can specify one or
more files as exceptions from a process.
The file specification has the format:
filenamelkeyword:comparison:date:time/exception (filename . . . )
where:
filename

Is a standard RSTSIE file specification.

keyword

Is either CR[EATION] or AC[CESS] and specifies that RESTOR
is to interpret the date and time as either file creation or access
dates and times.

comparison

Is either BEF[ORE] or AFT[ER] and specifies that RESTOR is
to process files created or accessed before or after the date and
time.

date

Specifies the date RESTOR uses to process files.

OPSER and Obsolete System Utility Programs

A-21

time

Optionally specifies the time RESTOR u~es t.o process files only
when you specify CREATION. Use the 24-hour format such as
14:49. The default is 00:01 on the specified date.

exception

Is EXC[EPT] and specifies that RESTOR is to exclude from
processing the specified files that follow. You can include all of
the previous elements in an EXCEPT phrase but do not include
another EXCEPT phrase. Separate multiple file specification
commas and enclose the list in parentheses.

RESTOR Interruption Commands

The RESTOR package includes interruption commands for your convenience. These commands enable you to detach, terminate, suspend,
and continue processing and to check the status of the run.
RESTOR shows it is ready to accept interruption commands by printing
an asterisk on the job's console terminal after the dialogue is complete.
You can type an interruption command as a response to a request in
the mount procedure or any time after the asterisk appears. Table A-4
provides a summary of the interruption commands.
Table A-4:

RESTOR Interruption Commands
Command and Meaning

ABO[RT]
Terminates processing immediately and returns control to your keyboard monitor.
CON[TINUE]
Continues processing after a PAUSE command.
DET[ACH]
Detaches job from KB:. RESTOR detaches if three conditions are met:
•
•
•

OPSER is running
The listing file is not on KB:
No messages are currently pending for this copy of RESTOR.

RESTOR is given a receiver identification of BACKnn, where nn is its job number. All
interaction with RESTOR is done through OPSER.
END
Terminates after processing the current file.

A-22

OPSER and Obsolete System Utility Programs

Table A-4 (Cont.):

RESTOR Interruption Commands

------------------------------

Command and Meaning

LAS[T]
Reprints, on KB:, the last text printed. If the program is awaiting a response, reprints
the question or prompt. If not, reprints the last message.

LEG[AL]
Prints (on KB:) a list of the commands and responses that are legal now. In the list,
**OTHER** means that a request for information from you is pending (for example,
Backup Set name). The response to such a request is any appropriate string. You
do not need to use quotation marks (") unless the response can be interpreted as an
interruption command. For example, you can legally name the Backup Set PAUSE, but
you must type the name in quotes ("PAUSE")
NOT[ICE]
Writes the specified text in the listing file. The NOTICE command has the format:
NOT[lCE] message
Message represents one line of text. No line terminators are allowed in the message.
OFF[LINE]
Same function as ABORT.
PAU[SE]
Suspends execution until you type CONTINUE. Any legal command typed during a
PAUSE is executed immediately.
STA[TUS]
Prints, on KB:, RESTOR status information.
TER[MINATE]
Closes the current volume at the end of the current file or at the end of the current
output volume, whichever comes first.
