Have you tried with the USS command:
tail -n "//'my.dataset.to.read'"
where n would be the number of lines
Please let me know if you could do it.

This is my output from the tail command in OMVS in tso, which I am sure can be
used in BPXbatch. So If you mount your dataset in OMVS / USS as /var/tailin
OMVS.TAILIN and a second one as /var/tailout OMVS.TAILOUT(empty) and issue the
command tail /var/tailin > /var/tailout, won't you get the best results ? No
messing around with other unix systems etc and code that someone needs to
rewrite in 2 year's time?

Well, if I were expecting to see the last "n" records output, then I'd
be pretty upset to get 0 when I knew that some were indeed output.

Well, I consider it to be "weird". Personal opinion, I guess. The
Dovetailed Technologies' "fromdsn" has an option to retain IBM
compatable RDWs in the output, or not, as an option. Of course, that
doesn't help if I want to output via JCL. So, somebody thought that
keeping RDWs might be important. Of course, I don't know how that option
would be architected in JCL.
