errsysw - division by zero

[Otto]

Hello Antonio,

Is there a reason why

“by default, division by zero yields zero”
is not included.

Why is the source code errsysw.prg in FWPPC in folder classes?

Thanks in advance
Otto

Otto,

It is included in errsysw.prg:

Code: Select all  Expand view

static function ShowError( oError )

   local cError := oError:Description
   local n
   
   if oError:GenCode == EG_ZERODIV
      return 0
   end

   ...
 

We use just one set of files for both FWH and FWPPC, so in order to have a different errsysw.prg from FWH, we need to place FWPPC one in classes folder.

Hello Antonio,
thank you. Yes you are right. But I don’t understand why if
tisch->menge is 0 the program freezes:
nPreis := tisch->wert / tisch->menge

I use now this code which works:
if tisch->menge <> 0
nPreis := tisch->wert / tisch->menge
endif

Best regards,
Otto
