It's been a while since I've done extensive work with KSAM files, but
I seem to recall that with CM KSAM, if the records do not need to be
retrieved in key order, you can significantly speed up the FCOPY by
adding ;KEY=0. I think that forces FCOPY to ignore the key file and to
sequentially read the data file. Lots less I/O that running down a
key's path in the key file and picking up the corresponding data
records.
