SORT-MERGE/XL Programmer's Guide

Sorting 

When you sort a set of records, you must specify the set of keys by which
the records are to be ordered.  The format of all records must be the
same.  These records may be submitted to SORT/XL individually or in one
or more files.  File input (as shown in Figure 1-2) is the most common
method of input.  For example, if you input two files, one file
containing information on current employees and another file containing
information on new employees, you can create a single output file with
all the employees sorted alphabetically by last name or numerically by
employee number.


          Figure 1-2.  SORT/XL Operations 

The intrinsics used for sorting are:

HPSORTINIT          Initializes SORT/XL utility and begins the sorting
                    operation (required).

HPSORTERRORMESS     Returns error messages.

HPSORTINPUT         Allows input to be by record (instead of the usual
                    file input).

HPSORTOUTPUT        Allows output to be by record (instead of the usual
                    file input).

HPSORTEND           Ends the sorting operation (required).

HPSORTSTAT          Prints sorting statistics.

HPSORTTITLE         Prints title information for SORT/XL.


NOTE  For sorting operations, use only the sort intrinsics.  Do not mix
      sort and merge intrinsics.
