Open License Computer Books

This book differs from the typical assembler text in that it is not a programming
manual, and it is not concerned with any specific assembler language. Instead
it concentrates on the design and implementation of assemblers and loaders. It
assumes that the reader has some knowledge of computers and programming, and it
aims to explain how assemblers and loaders work. Most of the discussion is general,
and most of the examples are in a hypothetical, simple, assembler language. Certain
examples are in the assembler languages of actual machines, and those are always
specified.
