The following program sorts the personnel files shown for
the last example. They are sorted by last name. The output records
are altered before they are output. Example D-4 SORTREC_OUTPUT Program $standard_level system
program SORTREC_OUTPUT
C
C This program reads the files TEMPEMP and PERMEMP, sorts them by last
C name, outputs them by record, alters the output recors, and prints the
C record to $STDLIST.
