ITYM "OS/360 FORTRAN G"; PCP, MFT and MVT all had the same compilers.
Those macros could be HASP II V3, HASP II V4 or JES2. My guess would be HASP II
V3.

AMBLIST will work, but PDS86 or StarTool will give you a more consistent
listing.

If your search string is less than 256 bytes then CUSE should work, if I am
reading th PoOps correctly. Set R0 to the length of the search string.

I don't recall seeing "at same offset" in the PoOps. I'll double check and, if
appropriate, send an RCF.

Keep in mind that UNPK swaps bits 0-3 of the right byte with bits 4-7.

Unpacking x'0123' gives you x'F0F132'; the OI then gives you x'F0F1F2'; what
you want is x'F0F1F2F3'. Or with an UNNPK length of 4 you get x'F0F0F1F2';
still not what you want.

Of course; the standard way to convert binary to hex is the UNPK/TR with a one
byte pad.
