DECUS 16-18bitCataUpd Feb72

This document is the DECUS Program Library Catalog, published by the Digital Equipment Computer Users Society (DECUS) in October 1971, with a February 1972 update.

It serves as a comprehensive listing of available software programs for various Digital Equipment Corporation (DEC) computers, specifically the PDP-7, PDP-7/9, PDP-8, PDP-9, PDP-11, PDP-12, and PDP-15 systems.

For each program, the catalog provides:

• A unique DECUS program number and title.
• Author(s) and their affiliation.
• A detailed abstract including its purpose and functionality.
• Information on minimum hardware requirements (e.g., memory, peripherals, specific CPU models).
• Dependencies on other software or operating systems.
• Storage requirements and any known restrictions.
• The source language (e.g., PAL, MACRO, FORTRAN, FOCAL, BASIC).

The programs are indexed numerically by PDP series and also categorized by function (e.g., Programming Language, Text Editing, Debugging, Utilities, Display, Data Management, Scientific Applications, Games, Plotting, Maintenance). Availability tables indicate that users could obtain programs in various formats including documentation (write-up), source code listings, or machine-readable media like paper tape (binary or ASCII), DECtape, LINCtape, Magtape, and card decks, with some listings available for a handling charge. The catalog also includes contact information for ordering and general inquiries.
