Don, 

Why would you not like to "see that source code posted here to God and the
world."?

This entire mess originated on this list with a description of the hole, how
to use DMPSYSOBJ to exploit it, and an MI program to do the same.  The list
members then went on to help Gene perfect it and to help him get the RPG
version of the program working.  Then it was promptly posted to the
Midrange-L list.

I can't help but think that we (the list) has done a bad thing here.  Look
at the number of folks that have compiled and are running this program at
their shop.  If it were only reported to IBM when it was discovered a long
time ago IBM could & would have fixed it.  Its too easy not to fix. 

I don't know if these messages are approved before being propagated to the
list members but I think they should be when they deal with security issues
and show how to exploit a security flaw complete with working examples.
Messages of that nature should be forwarded to the security folks @ IBM.
