- Yes, ARCH(11) for z13
- We found a program (only one) that needed 1.7GB to compile. And a lot of them
requiring up to 600MB. So we use REGION=0M & IEFUSI.
- CANCEL sentence when mixing 4.2 & 5.2 do not free used memory under certain
circumstances. We opened some PMR about this, but still
You will need to maintain compatibility with your lowest level of
hardware, prime or DR.

Why wouldn't ARCH(11) give the best performance? V5.2 has it? Of course, has to
be for a z13.
I'm not sure what you mean about REGION=0M. At least 200M will be needed, more
for large programs. See here:
Are there no internal IBM methods of asking?
There's the COBOL Cafe at the Compile Cafe:
https://www.ibm.com/developerworks/community/forums/html/forum?id=----2281,
a couple of compiler developers visit. There's also some advice posted there,
and elsewhere.
If the
- Test(DWARF): Increase size in library but not in memory, debug data is only
loaded at error/abend time.
- Best CPU usage if using Arch(9/10) on execution.
- Worst compile CPU/Time/Storage. REGION=0M, IEFUSI, ...
- Take an eye on latest maintenance, specially LE.
- Be aware of Arch level for
