No, I did not! And thanks a lot, it indeed contains all the info I need:

   at script.hop$f1() in ...\script.py:line 10
   at IronPython.Objects.Function0.Call()
   at IronPython.Objects.Ops.Call(Object func)
   at script.init_session$f0(Object busSettings, Object
fileNamePrefix)...\script.py:l
ine 7

so that with a little processing, I can make my it easy to read!!

Thanks a lot for the help.

Stan.
