- I am interested in rewriting some REXX code that currently runs under
- VM to take advantage of additional memory available under a larger
- virtual machine under VM/XA. I am curious if anyone has any comments about
- the potential for performance improvements (I realize that you are still going
- to be swapping out pages to disk). Some additional questions are:
-
- 1. Is their a limit on the program stack size under VM/XA or does it
- take advantage of the larger virtual storage as well.
-
- 2. Is there any documentation on how compound variables are "found." If I
- do a test on DATATYPE(LIST.Y.COUNT) and Y='HIPPO' to see if there is
- already an entry under 'HIPPO' how is this search conducted? The
- temptation with a large enough virtual machine is to use larger
- arrays with compound variables instead of writing to temporary files.
-
- 3. Are there any CMS commands to assist in taking full advantage of the
- larger virtual machine?
-
- Any help would be appreciated.
