>If the other app is a VFP app and you call it with the DO command, your variables will be visible to it. Otherwise, you would have to pass the variable to the EXE, and that EXE would have to be able to accept parameters -- RUN MyApp.EXE Parm1, Parm2. In VFP this works just like any other procedure call where you have the first line of code accepting the parms.

Sorry, probably no comma between parms:

RUN MyApp.EXE Parm1 Parm2
