Joe asks how to sort a file with long records.

<plug>

Likely the best way is with our Suprtool product.  We use our own sort
routines that have the advantage of:

1.  Using 1/2 the scratch space that HP's routines do,

2.  Sort about 20% faster, and

3.  Allow sorting of longer records (as of MPE/iX 3.0 the limit in
    HP's sort routines was 8192-byte records, but this may have
    changed in subsequent versions of MPE/iX).

</plug>

BTW, I'm not certain why Joe gets this specific error.  He mentioned
that HP's routines are in CM.  When I did extensive timing and testing
of HP's routines, I'm 99% certain that while sort.pub.sys is a CM
program that calls the CM sort intrinsics, they in turn just do a
cm/nm switch to the native-mode routines.  Thus all sorts are really
in NM, although there could be some restrictions for CM programs that
first call the CM routines.

Cheers,
