GAMS Support Wiki

There are various ways to enter additional GAMS command line options (e.g. ps = 9999 pw = 200):

• Within the GAMS IDE:
  • Use the parameter field on the right side of the top of the GAMS IDE
  • If you want to use these options permanently: File → Options → Execute → Use following additional parameters

• Using the command line interface:
  • Just add them to the GAMS call, e.g.: gams trnsport ps = 9999 pw = 200
  • If you want to use these options permanently: Add them to the file gmsprmnx.txt (Windows) or gmsprmnu.txt (UNIX)
• Use a parameter file:
  • Enter the options into an ASCII file (e.g gams.opt)
  • Activate this parameter file using the command line option:gams <model_name> pf=<parameter_file>
  • Hint: You can also use the GAMS option editor to generate and edit this file: Utilities → Option editor → File → Create option files →GAMS
