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.
