Hi, We've just upgraded to V4R5. An old MI program RTVQRYF (used for retrieving file definitions from a QRYDFN) will no longer work. We were and still are at security level 40. Previously it was patched by using SST to be in System Domain state. After the upgrade it was repatched but still will not execute. MCH6801 is issued saying the program is in system domain and cannot be accessed. If IBM have plugged this loophole, fair enough but how do I get the files used in QRYDFN without this trusty old program?
