IIRC, Batch LSR was developed at IBM by the BCP team; SMB was later developed by the DFdfp team. SMB is not BLSR under-the-covers, but it offers the same advantages.
SMB is the more modern solution. It has worked wonders at my shop. Just mind your REGION size. If you haven't converted some VSAM files to Extended Format, this is a good reason to do so. The VSAM Demystified Redbook is a good resource.

If only they also developed an alternative to CFCC with their neural cache tech, IBM Z would be boosted to hell and back. - KB ------- Original Message ------- On Tuesday, May 17th, 2022 at 5:39 AM, Michael Watkins <0000032966e74d0f-dmarc-requ...@listserv.ua.edu> wrote: ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
