[Message part 1 (text/plain, inline)]

Hi guys,
I am presently using version 7.1 on a Solaris box.  I downloaded 8.21 and really love the improvement in speed (almost 50% in some tests).  I am looking to replace the commercial product NSORT and would like this feature in the source instead of a wrapper.  If I have a file
XXXX300001XXXX
XXXX300002XXXX
XXXX300003XXXX
XXXX300003XXXX
XXXX300003XXXX
XXXX300003XXXX
XXXX300004XXXX
XXXX300005XXXX
XXXX300006XXXX
XXXX300007XXXX

NSORT keeps the 4 300003 records together in entry sequence.   My present work-around is to use a Python script that reads in the whole file and creates a pseudo-key that is 30000X plus an 8 digit sequence number (I process millions of records).  What I am thinking of is an -es (--entry-sequence) that would add a hidden -k to process on this internal sequence.  If I figure out how to do this on my own, I will submit it to you.


Thanks,
Danny Nicholas
