It seems that division by zero is not caught by VFP. In the command window, type ? 1/0 <return>, and you get a line of asterisks, right? (I'm running VFP9 SP2.) I have a form which evaluates a string expression and sends the result back to its caller. The only way I have found to catch division by zero is in a form method like this: LOCAL loEx As Exception, lnTmp As Double *!* THIS.cExpr is entered into an edit box on the form, THIS.nRetVal is the form return value loEx = .NULL. TRY THIS.nRetVal = EVALUATE(THIS.cExpr) lnTmp = 1/THIS.nRetVal = MOD(THIS.nRetVal, lnTmp) && catches error 1307 CATCH TO loEx ENDTRY IF ISNULL(loEx) THIS.Release() ELSE THIS.HandleException(loEx) ENDIF I think it wrong that VFP does not catch this error natively, unless I've missed a SET command or SYS() function. Any thoughts people? Laurie Alvey
