WISSIM: a simulation command language. Part II. Users guide for interfacing WISSIM and simulation models. IES report 40. [Rules for writing subroutine UMODEL, which does actual simulation]

WISSIM (Wisconsin Simulation) is a computer simulation control language designed to provide a convenient interface between computer simulation models and their users and to facilitate the writing of such models. WISSIM is linked with a user-written FORTRAN program that contains the code for the actual simulation. The control language has commands to modify and display parameters, print reports, save data, and graph data. This report contains the information necessary to interface a FORTRAN simulation program with WISSIM.
