There is nothing secret in the code as such. If you keep
it for yourself, I might mail the sources needed to
reproduce this. My mail address is available here:
"http://www.jescab.se/Kontakt1.htm" and I'll reply
with the files if you mail me.

I'll try to cut out as much as possible without loosing
the problem, so to speak.


The only switches I use is "/LIST/COPY/ANSI". Yes, this is
in ANSI fixed format since the code uses include files
from the IBM MQ distribution (client kit).

According to the .LIS file :
