Or the newer caching capabilities of SMB (System Managed Buffering), which is reputed to be more efficient than BLSR. I have not personally tested that assertion in a real-world situation, so I can't say if it is true or not.

I am a bit outdated in current systems services, so my first suggestion was to use EXCI into a CICS region or call a DB2 stored procedure which would act as a "server", but the question is - is there an easier way to accomplish this in pure batch? I am familiar with the cross-memory access but this would require heavy assembler coding, APF authorization, etc. all of which we are trying to avoid. -- This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
