Software Product Description
PRODUCT NAME: COS-310, Version 8, Commercial Operating System-310
DESCRIPTION:
COS-310 is one of Digital Equipment Corporation's
DATASYSTEM 300 Series Commercial Operating
Systems. It is an applications development tool for
EDP users who wish to implement data management
functions for small-to-medium size commercial applications. The software provides a minicomputer system configuration with the DIBOL Business Oriented
Language, system generation and maintenance programs, SORT IMERGE utility, and system monitor with
device handlers.
These programs constitute a self-contained disk-resident operating system. System features include:
direct data access capability, CRT cursor control,
User File Directories, and a large library of error messages.
COS-310 Monitor - COS-310 provides program operation master control through the system monitor.
For memory economy, the monitor resides in two
segments: one memory-resident and the other residing on the system device. The monitor includes a
comprehensive set of commands which control program loading, editing, and file directories.
The monitor contains handlers for all 1/0 devices supported by COS-310. The COS-310 monitor device options include line printers, CRT console terminals, and
floppy disk storage devices.
Editor - The system's editor consists of a basic
source language editor as part of the monitor. It is an
interactive editor with line numbers followed by the
information to be inserted, deleted, or changed. The
COS-310 editor provides automatic sequencing and
resequencing of line numbers by simple commands.
Input for the editor can originate from the console
keyboard. Output from the editor can be a listing of a
file on the console display or the line printer.
In the program development stage, the user can save
and quickly recall programs from the system device.
In operational mode, the user can batch commands
to the monitor into a file to be executed as a job
stream.
DIBOL Language - Digital Equipment Corporation's
Business Oriented Language (DIBOL) is translated by
the system's compiler "COMP" into DS300 interpretive code. Translation is from English-like source coding statements into object program routines.

he language permits data manipulation, arithmetic
expressions, subscripting, arrays, record overlay,
memory clear, file initialization, branching and tracing,
program chaining, and printing overlapped with processing.
The language syntax is divided into two sections: a
data definition section and a procedure section. The
procedure section of the language consists of
procedural verbs, each with comprehensive arguments. Some of the verbs are: PROC, XMIT, READ,
WRITE, GOTO, IF, CALL, RETURN, FORMS, STOP,
CHAIN, ACCEPT, DISPLAY, TRAP, and INCR.
SORT - COS-310 SORT is a multiphase sort which
can reorder a data file containing fixed length records
into a specified sequence. The user can specify up to
eight fields (with sub-fields) of a fixed length record
as a sort key. A file can be sorted in either the ascending or descending sequence of the contents of
the fields in each record.
The SORT has merge file capability. For a multivolume sort, each volume must be sorted and then
merged. Both SORT and MERGE are parameterized
by a "Sort Control Program."
PIP (Peripheral Interchange Program) - PIP is a utility program that transfers files from one device to
another. It can replace an existing file with a new file
and allow data files to be combined. It can accept
input from disk and produce output on terminal, disk,
or the line printer.
SYSGEN (SYStem GENeration) - SYSGEN is a conversational utility program that allows the user to configure or modify the current system using simple English statements. It provides the following optional
features: specifies disk and line-printer I/O handlers
in the system, takes new logical unit assignments
from the operator's terminal, and prints a table of
current unit assignments. The user can specify the
number of columns used on the line printer, either 80
or 132 columns. SYSGEN can transfer the system to
another device for installation startup.
DFU (Data File Utility) - DFU allows the user to deSignate and examine logical unit assignments. The
use of logical unit assignments for data files provides
data file device independence to the programs using
COS-310. Logical unit assignments may be .input to
DFU from the operator's keyboard, from a command

file stored on the system device, or from the edit buffer. The current logical unit assignments can be displayed or printed.

PREREQUISITE SOFTWARE:
None

PRINT - PRINT is a utility for the creation of report
programs. Using a parameter file which describes the
report, PRINT will generate a DIBOL program which
will produce that report.

COS-310/2780 Communications Software (on DS310
configurations only)

FLOW (FLOWchart generator) - FLOW is a utility
program designed to assist in the program documentation process. FLOW will generate a printed
flowchart from the DIBOL commands. The FLOW
commands may optionally be included in the DIBOL
source program.
Debugging Aids - COS-310 includes several features
which facilitate DIBOL program debugging. The DIBOL language itself incorporates a TRACE/NO
TRACE feature. When program tracing is enabled,
each DIBOL statement executed causes a line to be
printed containing the source file line number of the
statement. This is useful and time-saving when tracking the order of statement execution. In addition to
the TRACE feature, more complex program debugging techniques may be implemented using DDT (DIBOL Debugging Technique). The features of DDT include: breakpoint, variable examination, subroutine
call traceback, and iteration. Data records may be edited with the use of DAFT (Dump and Fix techniques).
DAFT provides the capability to search for, examine,
list and change records. DAFT may also be used to
make minor changes to a data file. The COS-310 program CREF (Cross Reference) is also an aid to program development. It provides an alphabetical listing
of all symbols used in the DIBOL program, the line
number where each symbol is defined, and all the
line numbers where each symbol is used.
File Conversion Program - FILEX is a utility program
that converts COS-300/310 formatted files stored on
DECtape or RK05 disk into OS/8 formatted files and
vice versa. In addition, FILEX can convert a COS-310
file stored on a flexible diskette or RK05 onto a flexible diskette in a format directly readable by the IBM
3740 series data entry terminal and the IBM
System/32. IBM files on flexible diskettes can be converted to COS-310 format provided they are single
volume and there are no bad tracks on the diskette
media.
