Abstract

Using macros with existing assemblers for microprocessors presents problems in that either a new assembler has to be written for each new microprocessor or the use of any existing assembler is restricted by the architecture of the original machine for which it was designed. This article describes a General Purpose Assembler (GPA) designed for use with a macro preprocessor and which gives flexible bit handling and error message generation. The assembler is capable of general application and is not restricted to byte orientated architecture. It can be used for microprocessors, micro programming and programmable logic arrays (PLAs).
