Would it be just easier to look into something like BLSR (Batch Local Shared Resources) or some other type of buffering of the VSAM file to improve access and save on physical I/O?

I am a bit outdated in current systems services, so my first suggestion was to use EXCI into a CICS region or call a DB2 stored procedure which would act as a "server", but the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.
