Ron,

If you want, visit
http://www.prycroft6.com.au/misc/3270.html
and read the text which talks about "parity".
(It's not really parity as such, but that word
is present in the text so you can search for it.)

You could also look at
http://www.prycroft6.com.au/misc/3270eds.html
and search for NOWAIT.

Even these days, processing files with DCBs (non-VSAM)
is much more common in application code than using
ACBs (as you do for VSAM, amongst other things),
so I would recommend trying out sequential I/O
first before looking at VSAM.

Cheers,
Greg
