This directory contains the Programmer's Manual for UNIX Program Generic PG-1C300 Issue 3 as published by the UNIX Support Group in March, 1977. UNIX Program Generic was the standard supported UNIX offering in the Bell System until the project was replaced with UNIX/TS and ultimately absorbed into the Programmer's Workbench line, leading to System III and System V. - Matt G.
