mod program is a stand-alone facility. It takes a model
description file in the "user-friendly" format described below and
creates a C language file `model.c' which you will compile and link
to the simulation program.
Mod allows the user to define
equations for the model, assign default values to parameters or default
initial values to model variables, and define scaling functions for both
the input parameters and the outputs variables.
Mod lets the user
create and modify models without having to maintain C code.
In Unix, the command line syntax for the mod program is:
mod [input-file [output-file]]
where the brackets indicate that the input and output filenames are optional. If the input filename is not specified, the program will prompt for both. If only the input filename is specified, the output is written by default to the file `model.c'. Unless you feel like doing some makefile programming, we recommend using this default since the makefile for MCSim assumes the C language model file to have this name. You have to have prepared an input file containing a description of the model following the syntax described in the following (see section 5.2 Syntax of the model description file).
On the Macintosh you double-click the `Mod' icon and enter the name of the model definition file at the prompt (on the Macintosh, names can include space characters).
