Problem:

In Dialog System how to control the First Window displayed?

Resolution:

Dialog System will display the first Window as defined in the screenset. This screen is configurable at design time via the Sceenset/First Window menu option.

If you want to control at runtime you can use the SET-FIRST-WINDOW function. This needs to be done in the SCREENSET-INITIALIZED function in Global Dialog.

For more information please see the online documentation on the SET-FIRST-WINDOW function.
