>what coding and sequence of events happen when you close a form with the X at top right of the form...?
>TIA

Since you've already gotten the answer, here's more info than you were asking for.

Assume you've got a close command button on a form. If you place code in its click event like this

IF ThisForm.QueryUnload()
  ThisForm.Release
ENDIF

and in the form's QueryUnload event

LOCAL llresult
llresult = < some logical condition >
IF NOT llresult
  NODEFAULT
ENDIF
RETURN llresult

You can easily keep the form from being closed while something like changes are pending.
