Description

This parameter indicates the maximum amount of 64-bit virtual storage to be used by report writers (currently, only the Dataset class SirtuneReport method). Report writers can use a lot of virtual storage which can adversely effect other users in an Online. This is why the default is 0 for any multi-user run.

Setting MAXREP64 to a non-zero value will cause report writers to try to use 64-bit storage which could relieve pressure on 31-bit storage. This will only work on Model 204 V6R3 and later, because earlier releases of Model 204 do not support 64-bit addressing. For more information on utilizing 64-bit storage, see the documentation for the specific report writer (for example the SirTune Reference Manual).

For single-user runs, it probably makes sense to make MAXREP64 very large (like 100000), as no report writer is likely to use that much, anyway, and the system-wide MEMLIMIT controls should prevent a job from using more virtual storage than it should.
