Was wonderring what all the fuss was about. Have used batch
files to call qb programs and got around the problem easily
enough. The only time my batch file cared what happened in
the qb program was when it had to branch either within
itself to another label or to another batch program. Why
not just open and close a file in qb such as :
OPEN "err_levl.1" FOR OUTPUT AS #1
CLOSE #1

You end up with a zero-byte file but the batch file can branch with:
IF EXIST ERR_LEVL.1 GOTO :LABEL
IF EXIST ERR_LEVL.x GOTO :ANOTHERLABEL
:LABEL
  .... (you get the picture)

This has always got me where I was trying to get to. Just remember to

IF EXIST ERR_LEVL.? DELETE ERR_LEVL.?

at the beginning of the batch file.

Might not be fancy, but then again, the best solution to a
problem is often right in front of us. Don't always try to
make things so difficult!

                             I guess there is another. <yikes>)
