No, these are VFP 6 apps. I think your approach
of running the apps minimized is interesting
though. How do you think updating the status
of the title bar
(e.g. _Screen.Caption = TRANS( lnPercent) + "% done" )
would compare to an @ SAY, therm bar or some such?

Keep in mind that these are batch mode programs and
will typically be processing 500K to 1M records?
