A complete interactive simulation environment GPSS/360-Norden

摘要

Norden's expanded and interactive version of GPSS/360 has been extensively improved through new data entry and storage capabilities, a new report generator, selective output display, and HELP blocks to enable model manipulation and to provide a "window" to view the simulation during its progress.

The data entry and manipulation system allows the user to input and display matrix savevalues through an IBM 2250 Display Unit. Titles may be placed on rows and columns to simplify the location of data items. A less elaborate system was developed for remote terminal and batch mode data entry.

The user can witness the progress of the simulation during the actual model execution. He then has the option to stop the simulation at any time, change parameters controlling operation of the model, and resume running of the model. This interactive feature opens vast new horizons for the world of simulation since with the appropriate equipment moving displays can be produced.
