PDP-11 MACRO-11 Language Reference Manual

This document is the official reference manual for the MACRO-11 relocatable assembler, designed for developing PDP-11 assembly language programs. It covers:

• Fundamental Concepts: Includes instructions for assembly passes, source program formatting, symbols, and expressions.
• Addressing Modes: Details on memory addressing and data manipulation on the PDP-11 architecture.
• Assembler Directives: Comprehensive descriptions of listing control, data storage, location counter control, and macro definition directives.
• Operating Procedures: System-specific instructions for running MACRO-11 on various Digital operating systems, including IAS, RSX-11M/M-PLUS, RSTS/E, and RT-11.
• Appendices: Provides details on character sets (DEC Multinational and Radix-50), a permanent symbol table, comprehensive error message codes, and recommended coding standards.
