Two simple DFSORT jobs (one COPY and one SORT).
One calls the COPY function using an INCLUDE which eliminates all the records.
The second calls the SORT function with the same INCLUDE eliminating all the
records so the final SORT is never executed.
The OPTION COPY does the same number of EXCPS but uses ½ the CPU and does
larger I/Os (3-4 times as large) as the SORT. It also runs 4 times as fast as
the SORT.
The problem with slow SORT appears to be related to the small number of buffers
used for the SORT function versus the OPTION COPY.
How do we allocate more buffers or storage for the SORTIN file?
Thanks,
OPTION COPY

And
INCLUDE COND=(26,6,CH,EQ,C'NEVERF')
SORT FIELDS=(22,4,CH,A)
