>I have an include file with some constants. In particular, MSG_ERROR is defined in this include file. I have a form class. In the form class I include that include file. I create a form based on the formclass. Some of the code in the form is "WAIT WINDOW MSG_ERROR". When this code is encountered I get, "Variable 'MSG_ERROR' is not found." I figured I forgot to compile everything. So, I did that. Same error. Perhaps the include file needs to be in the form also? I did that and recompiled everything. Same error. This is rather odd and I'm stymied on what to do next.

try using the the Include File option under FORM in the FROM desinger
for each form that you want to use your include file.
