COBOL Language

This reference manual describes the implementation of the COBOL language on the PDP-11 computer, adhering to the 1974 ANSI standard. It covers the four major COBOL divisions (Identification, Environment, Data, and Procedure), and includes information on language elements, compiler-specific extensions, and utility programs like SORT and REFORMAT. The document is intended for those with existing knowledge of the COBOL language rather than as a tutorial.
