If you'd stick to the heap, which is much more efficient, you can request
storage usage reports with quite a bit of detail.
+1. And if you can also diagnose the heap using tools like Fault
Analyzer and good old IPCS.

I doubt that you will get what you need that way. PL/I subaloocates
storage withing big blocks, and doing your own GETMAIN/STORAGE instead of
using native PL/I support may make matters worse.
MVS also suballocates storage, and I know of no GUPI to run the chains
with proper serialization and give the free/allocated counts.

Subject: Virtual Storage Manager - LDA.
Hi everybody,
I've a PLI program who does ALLOCATE and FREE of some based areas in order
to build and manage a dynamic tree.
I'm debugging a problem where it runs out of memory.
To control how much memory it's using I refer to LDA.
To be sure I changed the ALLOC and FREE with explicit (via a ASM module) to
STORAGE OBTAIN and RELEASE.
Here is the question:
I display the LDA structure before and after freeing some areas (few KB,
anyway more than zero) and I see no immediate difference.
Is the information in LDA updated by VSM with any delay ?
Thanks a lot in advance.
Max
