Subject: ZEX and ZCPR2

George,

       ZEX, the memory-based command file facility, is able to process
submit files, usually without change from the old form used with SUBMIT.
It was released with ZCPR2, and I have used it ever since, moving almost
completely away from SUBMIT and SUB2 (a version of SUBMIT with enhancements
that also came out wth ZCPR2).  The few cases I found it desirable to go
to SUB2 involved the need for a larger TPA, and ZEX may very well have
been able to handle it anyway.

       Your concern is valid ... if you have not tried ZEX with ZCPR2,
read the manual and try running a few ZEX command files.  I think you
will see the differences which attract me to ZEX and away from SUB2/SUBMIT.
The purpose of question 3 of the query was to see if anyone has an
application where ZEX absolutely cannot do the job and they HAVE to
use SUB2/SUBMIT.

               Rick
