SORT-MERGE/XL Programmer's Guide

Processing a Sort or Merge 

SORT-MERGE/XL is a set of utilities that allows you to sort a group of
records or merge several sorted groups of records into one.  The output
contains records presented in a specified sequence.  You may use
SORT-MERGE/XL as a utility and call it from the MPE XL command
interpreter (CI), or access it programmatically with the sort and merge
intrinsics from a program.

For each sort or merge operation, you must:

  Open the work area (Initialization).
  Specify input, output, keys, and collating sequences for the
  HPSORT-MERGE/XL utility (Initialization).
  Close the work area (Ending).

You may check errors and review statistics and title information as well.

Figure 1-1 shows you how HPSORT and HPMERGE intrinsics accomplish these
tasks.

detailed information about HPSORT and HPMERGE intrinsics.
