Abstract:

The language is a general purpose language which can be entered online on a DEC PDP-1140 minicomputer and cross compiled for the I8080. The cross-compiler follows the general pattern of most high level language compilers and consists of a scanner, a parser, semantic routines and code generation procedures. The cross-compiler accepts the input language and produces assembly language which is provided to a cross-assembler to generate machine code either on paper tape or a disk file. This code is then loaded into the I8080 for execution. The basic advantage of the high level language and cross-compiler is that it provides a user the capability to develop a program without having to know the details of microprocessor assembly language. Also, program development aids available on the DEC PDP-1140 minicomputer with an RSTSE operating system are made available to the microprocessor programmer. Author
