Thanks,
I hope you don't get tired of the Unix issues becaus I am really hoping I can use this for my reports.
Also just an FYI the Line terminator didn't show up until I concantinated the two files, I was there just hidden by the editor. If you want I can fix that for you, or use dos2unix (convert crlf to lf) and od -x filename (to make sure they are gone).
Thanks again
Bill Kruchas

Ok, I can certainly see where the line terminator thing might happen...
I do all my editing on Windows, so that makes some sense. I'll fire up
the VM later and get that script fixed.
As for the exception... it definitely shouldn't throw that exception...
when not defined, the preference should default to whatever it used to
(users home directory I believe)... I'll also check that in the VM
because this could be a Windows vs. Unix thing too as I didn't test the
code under Unix (this was contributed code from someone, and it tested
out fine under Windows).
Thanks Bill,
Frank
