Standard Output

The standard output from GAMS contains many components.  Here I discuss standard and optional components of the output file as well as error messages.  I will also cover procedures for controlling the amount of output produced.

This chapter does not cover the output that can be generated by the user through Display or Put statements.  Those topics are covered in the Improving Output via Report Writing and in Output via Put Commands chapters.
