HP RPG/XL Utilities-Part 1 XSORT

MPE Commands and Their Uses 

You must supply the necessary commands to your system in order for it to
perform the sort job you require.  Instructions concerning files, file
locations, and the name of the program are typical of the information
supplied by MPE commands.

An unsupported program similar to XSORT called SORT3 has been in
existence for some time.  A discussion of the commands for SORT3 as
compared to XSORT appears in appendix A.
