Thanks again,Gustav,
I tried, but it won't work. The moment of the second headering there had
been an output. So you get the error message just an iteration later.
Now I reduced the time my script needs. I will check out if it has
sufficient time on the productive machine.
If so, it won't be necessary to do a selfreferencing script.
Have a nice sunday
Sabine
