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.

I've been at shops that assign labels win ascending order. A few months of
maintenance and they're out of order. Even when they are in order they're
harder to understand than mnemonic labels.

rate in maintenance then it doen't matter.

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

Of course, and if your security profiles aren't right than you have more
serious issues than DYNALLOC.
