Since your code is after the call to READ EVENTS, you have to not only release the form you are working on but also issue a CLEAR EVENTS to give the control back to your program. So, your command button should look like this:

proc = "SCA"
THISFORM.release
CLEAR EVENTS

Hope I've helped you in any way!

>My question is when I press the command button to go to SCA.EXE I get a blank white screen and the SCA.EXE doesn't go any further. What do I need in my SCA.EXE opening form Init or Load to accept this calling program properly. And what do I need in the SCA.EXE form Exit button to return to this calling program?
