This tab allows you to specify the location of the main IDL directory, the default working directory, and any startup file to be run.
Use this field to select the location of the main IDL directory. The default is the location you specified when you installed IDL. There is no reason to change this entry. The location of the home IDL directory is shown primarily for informational purposes.
This field allows you to set the initial working directory for future IDL sessions. The General Preferences tab contains a "Change Directory on Open" option, which also affects the working directory.
Use this field to specify the name of an IDL batch file to be executed automatically each time IDL is run. See Startup Files for additional details.
On Motif platforms, you can disable the use of the startup file by selecting the Don't Use Startup File checkbox.
