1. "This manual left intentionally blank". Try a DATASORT. If you have that,
you probably have everything.
2. Yes, symbols are great. SyncSORT doesn't call them symbols as such, I think
they are "dictionary" or something like that.
I've been known to change Kolusu's inline comments to
If you don't need the physical file for anything except to extract from it, you
can just establish a SEQNUM for each selection, and just use an OUTFIL (or
more) with your selection by number. Saves the SORT, the creation of the new
file, and the processing of the new file, just cutting straight
Just some general suggestions that may be helpful:
1. ICETOOL has a number of commands that may make it easier to do what you
want. It's worth getting familiar with it. I've recently discovered that
SYNCTOOL handles my ICETOOL jobs just fine. I've not seen a byte of doc on
SYNCTOOL, so there
Thanks Bill, that put me on the right track. Another regular poster also
offered me some other options offline that might require fewer passes, which I
am exploring.
I will report back for the archives when I figure out what I am going to use.

Also, your initial BUILD creates the extra byte which is used. You can change
the subsequent BUILDs to OVERLAY which just change the one byte at column 5:
(will save you one BUILD per record, you'll notice).
If 220k+ were really large, you could also (since the test values are mutually
It doesn't matter where you physically locate the SORT control card, SORT will
execute after INREC.
You need to put anything which the SORT relies upon in INREC, and anything
which relies upon the SORT in OUTREC.

I am trying to partition a fairly large RECFM=VB dataset (220K+ records) by
various characteristics of the records using a unique identifier byte and a
SEQNUM. The goal is to be able to subsequently extract in a second pass some
"count" number of records by "type" to create an extracted sample
