I ran into something in code recently that I never do personally. It just 'bugs' me. I've never done it and when I saw it, I stepped through the code to verify what actually happens:

SCAN
   IF .T.
      RETURN  && exits scan..endscan and returns to calling program
   ENDIF
ENDSCAN	
*--.T. case never hits here

>>I believe that Basic (and perhaps others) have a WHILE - WEND where the code is always evaluated at least once and the loop control is at the bottom.
