I am running the IDL Workbench 7.1.1 with Windows XP-Pro. I would like to start the Workbench from the command line and specify the Workspace. Is this possible? If you like details: I repeatably run the same IDL sav file on multiple machines at the same time without an operator. This sometimes fails because there are not enough IDL licenses. I can recover: after one hour, the calling program gives up, kills IDL, and restarts it. But, I have noticed that if I start the IDL Workbench first, then I have "my foot in the door" and the automated process usually has enough licenses to run. So, just to save time, I would like the automated process to do the initial IDL Workbench startup. Since this is on multiple machines, I use a different workspace for each computer. TIA, Sam.
