PROGRAMMING LANGUAGE FOR AUTOMATIC CHECKOUT EQUIPMENT. VOLUME I. ADAPTED PLACE FOR THE RCA DEE.
Abstract
This report describes PLACE, a language for the programming of automatic checkout equipment, and tells how it can be used to write programs for the RCA DEE, an automatic checkout machine controlled by a digital computer. The language is such that any program can be written for the DEE without resorting to the use of actual machine language. The stimulus and measurement equipment of the DEE can be programmed at the machine language level through the use of special statements involving mnemonic symbols and numeric values. The controlling computer can be programmed by the use of algebraic language statements, similar to those found in FORTRAN and ALGOL, or at the machine language level by using special statements available for that purpose. In addition to the checkout-machine-cnntrolling language, the programmer is provided with language to control the compiler. With this language he can define new statements which may be in a PLACE determined format, or as English language-like as he wishes to make them. The compiler-control language has facilities for writing arithmetic and Boolean expressions; logic decision tables; and compiletime subroutines, called forms, which may be called recursively.
