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 “SORT/XL Operations”) 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.
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. |
