Doing CHGPGM USRPRF(*OWNER) when observable info is *NONE...

[CWilt@xxxxxxxxxxxx]

Trying to fix problems with security on an old version of BPCS and I've run
into a snag.  I've got a list of 76 programs currently set USRPRF(*USER)
with no observable information.  So when I run a CHGPGM I get a CPF0541 -
Program xxxx in library xxxx not changed.  Apparently a program must have
observable info for CHGPGM to work.

Unfortunately, I don't have the source to some/(all?) of these programs.

It would seem that being able to change from USRPRF(*USER) to USRPRF(*OWNER)
shouldn't technically require observable info and I did find the following
post in the newsgroup:
"If you're referencing the adopted authority of USRPRF(*USER) or of
USRPRF(*OWNER), then service tools can be used to patch the attribute
bytes of the Object Specific Header (XPMHDR) and "brute force" the
USRPRF(*USER)"

I assume the reverse is true (*USER ---> *OWNER) but does anyone have more
info one this method?  I suppose this isn't possible to do via API's?

Thanks,
