Description

This parameter indicates the maximum amount of 31-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. With the default, no report writer will be able to run in a multi-user Online.

Generally, report writers will be invoked in single-user runs, in which case the default of 1024 (megabytes) should be adequate for most purposes. If you find that you are running out of 31-bit storage, you can try to get the report writer to use 64-bit storage by setting MAXREP64. 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).

The maximum allowed value for MAXREP31 is 2048, because that is the maximum amount of storage that may be addressed using 31-bit addressing. If MAXREP31 must be set to a value greater than 1024 to get reports to run, contact Technical Support, since this would suggest that the report writer is getting close to some architectural limits and might need to be restructured.
