Hello Douglas,
I'm just wondering... why on earth are you using directories with # in it? # is a comment in unix, so if you want to be handled correctly either you don't use it, or you put quotes in your path.
I mean you wrote:
/products/ars/dev/bin/arsload ?a ?TEST1? ?g ?AGTEST? ?h ?TESTDB1? ?n ?v ?f /home/#1510/TH/CNNOTICE.PC7.PSK
But I would write like this :
/products/ars/dev/bin/arsload ?a ?TEST1? ?g ?AGTEST? ?h ?TESTDB1? ?n ?v ?f "/home/#1510/TH/CNNOTICE.PC7.PSK"
I don't know if it will help, but at least from an unix point of view, it is safer!
Now, you are on z/OS, and I cannot help you more than that, sorry :-( I wish I can take the time to learn about z environments :-D but maybe in another life!!
Good luck,
Sincerely yours,
Alessandro
