big your linkage section is, COBOL does not allocate storage for it.
COBOL has supported passing BY CONTENT (not BY REFERENCE) since about 1997
and BY VALUE for a decade and a half or so.
We are developing a big batch COBOL program which uses lot of
storage. There are many arrays which are loaded from DB2 tables. The
number of occurrences for all these arrays which vary from run to run.
Hence we thought instead of using working storage section for these
arrays, we will use

Does anyone know of a facility similar to GFS trace for tracing above the bar

I have a program that analyzes GFS trace output which makes short work of
diagnosing memory leaks. It also reports storage usage by TCB and subpool.
But I would like to be able

problem state, non-authorized application. LE will never ask for
anything other than low private subpools, i.e. task-owned, fetch

AFAIR LE use subpool 2 key 8. However it's possible to allocate CSA/ECSA
while running in key8. Since z/OS R8 or R9 you can deny such kind of
allocations. Before it was an undocumented option.

You can use the getrlimit service to increase the region limit up to
the hard limit, which IIRC is set from BPXPRM00 or the user profile.
There is an example of invoking this from REXX at

So you would invoke that with setrlim rlimit_as
