The Compiler for the Programming Language for Automatic Checkout Equipment (Place). Part I: Place Language and Compiler.

摘要

PLACE (Programming Language for Automatic Checkout Equipment) was developed to provide (1) a language that could be used by engineers to program a variety of test systems, and (2) a language for which compilers could be developed quickly and inexpensively. The approach taken was to develop a basic programming language with which individuals closely associated with a particular checkout machine and checkout environment could easily develop both the statements to be used by engineers for checkout programming, and the compiler to translate the statements into code for the test system. Associated with the PLACE language is a computer program called the PLACE Processor which operates on the IBM 7094 computer. This program forms the major portion of the compiler for a checkout system. This report is devoted primarily to a formal description of the PLACE language, the detailed documentation of the PLACE Processor, and to a discussion of the use of the Processor in compiler development.
