File»New Job (Ctrl+N)

You can select New Job from the File menu. This will bring up the GENER launch panel so you can set new options for GENER to use. This includes running GENER against a different CL file or post processor. If you want to restart GENER using the same settings you currently have, use the Restart command instead.

Stops post-processing and returns to the launch panel where new options or an entirely different CL file can be specified.
