Hi Njal,
UNDELM has one machine instruction that has to be changed with SST. In the source, scan for 'MOD:' You should find
SETSPP SRCMSP, ADDR; CPYBLA ADDR, PADDR; /*MOD: Mod preceding ins to copy PADDR to SRCMSP */ /* 3B54 */ /* F86100C8 STD 3, 0XC8(1) */
The F86100C8 is the new machine instruction. However, it will probably be different for your pgm because the compiler probably used a different register. This shows it using register 3, but I just recompiled it (on V5R1) and it used register 23.
You can dump the pgm with SST, specifying "Format dis-assembled code" and find the instruction by comparing MI instruction numbers from the MI listing. In the version that's currently on iseriesnetwork.com, it should be instruction 1F9.
The dump for 1F8 (the SETSPP) and 1F9 (the CPYBLA) should look something like this (ignoring the 2 address columns at the left):
003750 3B1FFE48 ADDI 24,31,-440 1F8 003754 FB0100C8 STD 24,0XC8(1) 003758 EAFFFE30 LD 23,0XFE30(31) 1F9 00375C FAFFFE48 STD 23,0XFE48(31)
In this case the instruction at 00375C should be changed from FAFFFE48 to FAFF00C8:
00375C FAFF00C8 STD 23,0XC8(31)
If it's different, you can send me the dump for those instructions and I'll tell you what the new instruction should be. You can email me off-list if you want:

We have been using the excellent UNDEL utility from time to time
withjout any problems. Now with a new box running V5R3 and system value QVFYOBJRST set to 3, the UNDELM program wasn't restored.
I managed to compile the program, and patching it to system state (security level 40), but it returns BADRRN no matter what we try.
Any suggestions?
