GPSS/360-Norden, an Improved System Analysis Tool

The General Purpose Simulation System (GPSS)/ 360 program used with the IBM System/360 computers has been modified to permit larger models, data libraries, and an interactive user service. The major improvements of the GPSS/360-Norden are the following. 1) Models of any size may be run by using direct access devices to store sections of the model. 2) The models can interact with data banks stored on direct access devices. 3) The model output can be presented to the user on a 2250 display it as well as on the conventional printer. 4) Model generation and debugging has been improved using the 2250 display unit. Complete compatibility has been maintained and normal use of GPSS/360 is unaffected by the changes and additions.
