The pointer stored in the DMEPT has to come from the *SEPT, so just update the QINSEPT before the file is opened. I would make the intercept program a CLP that does nothing more than a TFRCTL to the OS DB program, in order to avoid impacting any other work that must be done while debugging. Or after the open, but before the I\O request, the DM EPT could be updated in the ODP.

Hack the QINSEPT?!? On a production box?!? Uh, even if I knew how (I had to read the aforementioned tutorial from Leif, just to know how to dump it!), it's not something I'd care to risk.

Hacking the ODP would be a little more reasonable, IF I had the slightest idea how to do that in an ILE program.

The first recompilation only yielded a few ideas that DIDN'T work:
If I changed the option list on a .DMCGETD (RPG SETLL) to "Read First," the program crashed.
If I set the target RRN to zero or a negative value, the OPM RPG test got nothing, and the MI app got the known-excluded first record.

But I've got another recompilation cooking right now (it just finished, but I've been off-duty for 5 minutes already!), for tomorrow morning, that's got the option list for .DMCGET (RPG READ) opened up for manipulation in the debugger.
