Abstract : OPS is an on-line system developed at Project MAC. The present work provides a powerful and simple way to perform numerical manipulations and calculations within OPS. The program package is called CALCULAID, and provides a method of executing algebraic assignment statements, of which MAD and FORTRAN assignments are a subset. When this assignment-statement ability is coupled with other features of the OPS system, most of the ability of a compiler language is provided. Because the programs written in OPS are executed interpretively, OPS-3 programs can be changed and re-run immediately, without being recompiled. The applications of CALCULAID to the analysis of a round-robin scheduling model and to a process-control problem are discussed, and conclusions are drawn regarding the suitability of running computational programs in an interpretive mode.
