PAL-11R Assembler

This manual, first printed in 1971, provides detailed documentation for the PAL-11R assembler used with the PDP-11 Disk Operating System (DOS). It covers the assembly language syntax, assembler directives, addressing modes, and operating procedures for PAL-11R. The document also includes information on relocation, linking, error codes, and appendices detailing ASCII character sets and specific instruction formats for the PDP-11 architecture. It assumes the reader has familiarity with the DOS monitor and the PDP-11 instruction set as described in the 1971 PDP-11 Handbook.
