DECsystem-10 ALGOL Programmer's Reference Manual

This document is the official Programmer's Reference Manual for the DECsystem-10 implementation of the ALGOL-60 programming language (Version 3B). It serves as a comprehensive guide for both users familiar with ALGOL-60 and those experienced in other high-level scientific languages.

Key contents include: - Language Structure: Detailed descriptions of symbols, identifiers, declarations, and program structure. - Programming Constructs: Coverage of constants, expressions (including operator precedence), statements, assignments, control transfers, and conditional statements. - Control Flow: Documentation on loop structures, including FOR and WHILE statements. - Data Structures: Detailed information on arrays (including those with dynamic bounds) and strings, including byte manipulation capabilities. - Subprograms: Information on procedure definitions, parameter passing (value vs. name), and advanced topics like recursion and forward references. - Operating Environment: Guidelines on input/output operations, peripheral device management, the DECsystem-10 library, and running/debugging programs. - Technical Notes: Insights into the implementation details and deviations from the standard ALGOL-60 Revised Report.
