Oops. I left out the actual word PERIOD at the end of the second sentence. Oh, well the period character served as a surrogate. That's my story... :)

>>>Hey UT folks -

>>>Did you know that when you issue a SCAN/ENDSCAN VFP automatically flips a SELECT back to the correct file when hitting the ENDSCAN without you having to explicitly doing so?

>>>Here's an example program:

>>>SELECT j1

>>>SCAN
>>> SELECT j2
>>> LOCATE FOR ord = j1->rec
>>> IF NOT FOUND()
>>> APPEND BLANK
>>> REPLACE ord with j1->rec
>>> ENDIF
>>>ENDSCAN
>>>
>>>Now I would have expected this to bomb, because I didn't issue a 'SELECT j1' after the REPLACE and there's no 'ord' field on the 'j2' file. But when the program hits the ENDSCAN, it reverts to 'j1' automatically!

>>>Please someone tell me this is new and not been around since VFP 3 or FoxPro 1.0. Yeesh!
