Software Product Description
PRODUCT NAME: TOPS-20AN, Version 3A, System Software Package
DESCRIPTION:
The TOPS-20AN System Software package is included with each T -Series System. The TOPS-20AN System Software package is a multiuser, multiianguage
interactive processing system with multistream batch
capabilities. The system supports between 8 and 128
simultaneous interactive users, depending on system
load and configuration with concurrent multistream
batch processing. The TOPS-20AN System Software
package includes:
• the TOPS-20AN operating system
• the RSX-20F operating system
• EXEC, the TOPS-20AN command language executive
• EDIT, the TOPS-20AN editor
• GALAXY, the TOPS-20AN batch system
• the MACRO assembler
• the LINK overlay loader
• system utiUties
The TOPS-20AN Operating System supports ARPANET Host Interfaces (local and distant). It includes:
• The Initial Connect Protocol (ICP) to establish a fullduplex connection between the host computer and
the network node.
• The Network Control Program (NCP) to establish a
host-to-host interface upon which function level
protocols are based.
• TELNET (Telecommunications Network) to allow a
terminal at one host (or a TIP) to establish a logical
connection to a foreign host and look like a local
terminal to that host.
• RJE (Remote Job Entry) makes it possible for a
host to submit a job for execution at another host.
• The File Transfer Protocol (FTP) to allow transferring files between ARPANET sites.
• A Mail Protocol for both local and network users.
The package optionally supports FORTRAN, COBOL,
ALGOL, APL, BASIC, and CPL high-level language
processors. The DBMS (Data Base Management System) package is also optionally supported, interfaced
to either FORTRAN or COBOL. The SORT program is
an additional option which interfaces to COBOL.

The system features:
• Virtual memory system with multiprocess job structure

operation
The TOPS-20AN operating system provides a virtual
memory user environment of 256K 36-bit words. This
virtual address space is demand-paged in 512-word
pages. The user environment is structured to provide
a multiprocessing job structure that services complex
applications as well as simple ones. Several forms of
interprocess communication are provided:
• IPCF - interprocess communication facility used to
pass messages between processes
• PSI - pseudo-software interrupts are generated by
the system for event posting between processes
• ENQ/DEQ - a resource queuing mechanism for
the synchronization of two or more processes,
commonly used for record-level interlocks
• Page Sharing - system and user level code and
data sharing on a per page basis
• Process Control - direct functional control of an
inferior process by its superior; used to implement
the TOPS-20AN EXEC and available for user application subsystems
The TOPS-20AN file system is a general purpose
named file system that provides:
• Mountable disk structures
• Up to 4,000 user accounts/directories per structure
on 2040T or 2050T or 12,000 user accounts/directories per structure on 2060T or 1090T
• Multilevel directory structures
• Interuser security through directory and file access
protection mechanisms
• Interuser cooperation specification through the user
group definition facility, allowing arbitrary definition
of user groups that wish to have common access to
files
• Simultaneous update capabilities within a file, allowing two or more cooperating users concurrent
update access to a file

facility, which eliminate the need for file name syntax checking in user programs and provide file
naming consistency between programs
• Centralized file operations monitor facilities, which
include easy-to-program sequential accessing in
byte or string modes
These capabilities are provided to the user through
TOPS-20AN system calls.
The TOPS-20AN operating system performs process
scheduling, memory management, and file system
management. It also provides the environment for the
batch system's queuing, job scheduling, job accounting, and device spooling operations. Provisions exist
to allow allocation of specific percentages of the central processor to specific jobs.
The TOPS-20AN operating system enhances system
efficiency by optimizing system resource utilization.
Among these optimizations are disk optimization, tape
throughput optimization, demand paging, and easy
re-entrant programming facilities. In addition, the
TOPS-20AN batch system provides performance and
efficiency in the virtual memory environment.
The TOPS-20AN operating system supports hardware
error detection and recording in a system disk file. A
system error-reporting program is provided which
processes this error file to enable DIGITAL service
personnel to monitor system performance.
The RSX-20F operating system Version VB12-12 controls the front-end processor and communicates with
the T-Series System processor. RSX-20F controls the
unit record equipment and the asynchronous terminal
lines. The asynchronous terminal lines can be either
local or modem controlled (dial-in). Automatic baud
rate detection is supported on modem-controlled
lines at 110, 150, and 300 baud. RSX-20F also provides the system console facilities.
The TOPS-20AN EXEC implements the system command language for interactive and batch processing.
It provides command level facilities for contrOlling
creation, compilation, execution, debugging, and
deletion of user programs and their data. Commands
exist to allow user assignment of resources, and to
provide user/operator and user/terminal communications. The TOPS-20AN EXEC also provides file handling commands, operator level commands, and a
number of system information commands. Additional
user level system facilities are provided to further aid
