Change Program's state to *SYSTEM premanently to survive a RSTOBJ

[Matías Centeno Lozada <m-centeno@xxxxxxxxxx>]

Hi everybody.
As we know, some programs (like UNDELCB & UNDELM from WRKDBF tool or CHGPWDTMC 
& RVSETUP from GOFASTER) had been 'patched' to be *SYSTEM state programs, but I 
don't know how the 'patch' was done to cheat RSTxxx commands and avoid that 
i5/OS change program state back to *USER.

I tested to 'patch' one of my MI programs, save it and then restore it, but the 
program state is changed back to *USER.
I tried saving the patched program with QSCMATPG and then restoring it with 
QSCCRTPG, but program's state is changed back to *USER too.

Anyone knows how to change program state permanently and avoid that i5/OS know 
that the program had been patched ?
May be exist some undocumented API or program in QSYS to do it.

Leif, I'm sure that you know the answer.

Regards, Matias.
