Thank you, John.

>The technique means ShellExecute doesn't need to be Declared unless/until it is needed, and you shouldn't ever see the "function not found" as long as the VFP function is in a SET PROC or included in your project. The function is also only ever declared once rather than repeatedly as you sometimes see when people want to make sure it is declared, since DECLARE definitely carries a performance hit.
