Describes the format of linkable, relocatable, and absolute object modules for binary computers of arbitrary word size and architecture. Does not specify the source language features to be supported by way of MUFOM modules; the structure of relocatable code libraries; the format of the optional binary equivalent; algorithms for linking, relocating and loading; the architecture of the host machine and the architecture of the target machine, including word size, size of memory, memory organization or instruction format. Covers definitions, references, introduction, commands, free-form syntax, basic constructions, notation used for syntax definitions, elementary syntactic objects, expressions, types of operands, functions with no operands and much more.
