I know that for BLSR the HBUFND and HBUFNI parameters originally allocated memory in "extended storage" when that actually existed as a hardware option.
In z/OS today (V3.1), given that RMODE31=ALL is also specified, are HBUFND and HBUFNI buffers allocated above the 16M line but below the 2G bar just like BUFND and BUFNI, or are HBUFNx buffers allocated above the 2G bar? I am trying to determine if it is worth using BLSR HBUFNx parameters for NON-extended VSAM KSDS reference files on somewhat memory-constrained below 2G systems (available PRIVATE < 1148M) for batch applications that use lots of reference data READ's, or instead should I just increase the BUFND and BUFNI values within the existing memory constraints below 2G?
