As far as I know, reading a physical sequential (or partitioned dataset member) in reverse order can only be done using BSAM (via the BSP macro). Not that many applications require that mode of processing. But if one does, well then, that appears to be the only option. Mind you, there are some restrictions inherent in using BSP, as the manual explains. The COBOL manual states that you can process a QSAM tape dataset in reverse order by doing an OPEN REVERSED, but I suspect that the dataset will actually be processed using BSAM, not QSAM.
