Can anyone tell me how the BSAM POINT macro works for tape. Is there a device command that will just skip say 1000 blocks with only one device end returned and with no data transfer over the channel (what I really hope happens)? Or does it just READ 1000 blocks without placing them in memory? The READ version would seem absurd enough to make the whole option rather pointless (Oh that's bad) for tape.
About to have a customer invest quite a bit of time/resources here and I'd sure like to be certain of gaining advantage in run time and resource used. I've tried the archives and got hundreds of matches on several terms tried. Cannot seem to figure how to winnow them down. Also looked at the POPs manual section on I/O and I'll bet it is in there but I could not find it. I would really love to be embarrassed at how quickly and easily someone points me to it. A sample program would of course be ideal. :-) ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
