You're welcome, glad I could help. Sometimes the oldies are still goodies. <g>

>>if your expression evaluates to .T. then the control will receive focus, if on the other hand your expression evaluates to .F. then the control will not receive focus.

>This has also solved another problem I had in my approach. I had to manually KEYBOARD tab and backtab depending on the last key stroke, now with when() returning .f. VFP handles it.
