If you ant an "example" look at CBTTAPE.ORG and look for either DITTO
or DEBE and take a look at the source.
I know it uses EXCP instead of BSAM but it should give you a flavor.

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. :-)
