Software Product Description
PRODUCT NAME: DECSYSTEM-20 COBOL-58, Version 12, ANS-68 COBOL Compiler with SORT/MERGE, Version 4
DESCRIPTION:
The DECSYSTEM-20 COBOL compiler is an implementation of the COBOL language based on the
ANS COBOL X3.23-1968 specification. It is designed
to work in a batch or interactive environment. In a
batch environment, series of compilations, program
loading and execution directions and data can be
submitted for processing, leaving the user free to do
other work while the batch job is running. COBOL-68
provides an interactive debugging facility. The user is
able to follow the progress of the program by causing
the program to pause at ay desired step during execution. The user can then examine and modify the
data before continuing execution. The user can also
modify the source program stored on disk, recompile
and begin execution again. Listings produced by the
compiler contain many documentation and debugging
aids. English diagnostic messages are imbedded in
the source listing at the point of error. In addition, the
listing can also include at the user's discretion, a
complete map of the object program, and an easy-toread listing of the compiled code. The latter is presented in the form used by MACRO, the DECSYSTEM-20 assembly language translator. All object code
is expanded to list the machine mnemonics and user
defined names in addition to the binary machine code
(in octal). An implementation of the COBOL SORT
and REPORT WRITER statements is provided.
A complete ISAM (indexed sequential access method)
package is included in the COBOL object time system. This package allows the user to sequentially or
randomly access data stored on a random access device. The time required to access a file is not affected
by the number of additions made to the file. The
technique of "chaining" records is not used. Instead
the index to the file is updated to minimize the number of accesses necessary to retrieve records.
On-line Debugger:
The on-line debugging package permits user interaction during the execution of a program. No changes
to a source program are necessary to use the facilities of the package. If the user desires to use this
facility, it is loaded with the object program when execution starts. The user can specify pOints within the
program at which to pause during execution.
During these pauses, the user can examine the
contents of any data fields to check the progress of
the program, and, if desired, alter those contents be-

fore proceeding. All references to data and procedure
items are made by using the name in th source program. The user talks to the debugging package using
familiar names than truncated or substituted names.
RERUN:
The RERUN feature allows the user to save the status
of a job periodically. In the event of later disruption
the job can be restarted from the point of the last
status save, instead of starting again from the beginning.

Subroutines:
COBOL may call subroutines written in COBOL, FORTRAN or MACRO.
SORT IMERGE is a disk sort utility for the
DECSYSTEM-20 which operates stand-alone or in
configuration with COBOL-68. SORT IMERGE reorders the records of:
• ASCII files
• SIXBIT files
• EBCDIC files
• Binary files produced by COBOL or FORTRAN
in a sequence determined by the sorting parameters
prepared by the user.
SORT IMERGE automatically controls the use and allocation of disk work space and memory work space.
The user can also specifiy memory limits.
SORT IMERGE provides error diagnostics and statistics upon completion.
The MERGE capability permits the merging of sorted
files into a single sorted file. This function can be
invoked
either
in
the
stand-alone
use
of
SORT IMERGE or via the COBOL MERGE verb.

MINIMUM HARDWARE REQUIRED:
DECSYSTEM-20 with 128K words of memory.
OPTIONAL HARDWARE SUPPORTED:
Supports any device supported by TOPS-20 System
Software.
PREREQUISITE SOFTWARE:
TOPS-20 System Software, Version 1 or later
OPTIONAL SOFTWARE SUPPORTED:

ADDENDUM
SOFTWARE SUPPORT CATEGORIES
Each software product (hereinafter 'SOFTWARE') with a designated Support Category A or B in the applicable Software Product
Description (SPD) existing at the time of order will be the current release at the time of delivery and will conform to the SPD.
DIGITAL's sole obligation shall be to correct defects (nonconformance of the SOFTWARE to the SPD) as described below. Any
SOFTWARE with a deSignated Support Category C will be furnished on an 'as is' basis.
For SOFTWARE with a deSignated Support Category A or B, DIGITAL will provide the services set forth below without additional
charge.
CATEGORY A
1. Upon notification by customer to the nearest DIGITAL office that the computer system, including all required prerequisite
hardware and software, is ready for the installation of the SOFTWARE, DIGITAL will install such SOFTWARE in any location
within the contiguous forty-eight (48) United States, the District of Columbia, or a country in which DIGITAL or a subsidiary
of DIGITAL has a software service facility. The notification must be received by DIGITAL and the system must be ready for
installation within thirty (30) days after the delivery of the SOFTWARE to customer or DIGITAL will have no obligation to
install. Installation will consist of: (1) verification that all components of the SOFTWARE have been received by customer, (2)
loading the SOFTWARE, and (3) executing a DIGITAL sample procedure.
2. During the ninety (90) day period after installation, if the customer encounters a problem with the current unaltered release
of the SOFTWARE which DIGITAL determines to be a defect in the SOFTWARE, DIGITAL will provide the following remedial
service (on site where necessary): (1) if the SOFTWARE is inoperable, apply a temporary correction (TC) or make a
reasonable attempt to develop an emergency by-pass, and (2) assist the customer to prepare a Software Performance
Report (SPR) and submit it to DIGITAL.
3. During the one (1) year period following installation, if the customer encounters a problem with the SOFTWARE which his
diagnosis indicates is caused by a SOFTWARE defect, the customer may submit an SPR to DIGITAL. DIGITAL will respond
to problems reported in SPRs which are caused by defects in the current unaltered release of the SOFTWARE via the
Maintenance Periodical for the SOFTWARE, which reports SPRs received, code corrections, temporary corrections, generally
useful emergency by-passes and/or notice of the availability of corrected code. Software Updates, if any, released by
DIGITAL during the one (1) year period, will be provided to the customer on DIGITAL's standard distribution media as
specified in the applicable SPD. The customer w!1I be charged only for the media on which such updates are provided,
unless otherwise stated in the applicable SPD, at DIGITAL's then current media prices.
CATEGORY B
During the one (1) year period following delivery, the services provided to the customer will be the same as set forth in 3 above.
CATEGORY C
SOFTWARE is provided on an 'as is' basis. Any software services, if available, will be provided at the then current charges.
DIGITAL shall have the right to make additional charges for any additional effort required to provide services resulting from
customer use of other than current unaltered release of the SOFTWARE operated in accordance with the SPD.
