This paper describes the interactive debugging feature of GPSS/H (1), a new implementation of GPSS for IBM 360/370 computers. In GPSS/H, interactive debugging of a simulation model is carried out by means of a simple, but powerful command language. Commands are provided to selectively display model data on a terminal, to set breakpoints at arbitrary points in a model, and to step through a model one or more blocks at a time. An overview of the command language and an illustrative example of its use are presented in this paper.
