>I just reconfirmed what I said earlier. If I compile a vcx in VFP 9 with the line 'Set ReportBehavior 90' and then , without recompiling the vcx, include this vcx in a vfp 7 exe [build without recompile all turned on] it will run without error. I do not understand the dynamics of this...

You are correct, it doesn't error in VFP7 when it's in code. It does from the command window, but not from code that's compiled in VFP9.
