Using the model return value for error handling

Description

The default return value of a Mosel model at the end of its execution is 0. Other values may be set with the procedure exit as shown in the file exitvalue.mos. The model return values can be used by the calling application (exitvalue.c, runexitvalue.mos) for the implementation of error handling routines.
