Three Types of Sort 

Figure 1-2 illustrates XSORT's sort capability--Address-out, Record-out,
and Count-only.


          Figure 1-2.  Three Types of Sort 

Address-Out Sort (SORTA) 

The output from an Address-out sort job consists of 4-byte binary
relative record numbers of the records in the input file.

An Address-out sort allows you to process a file in sorted order without
using up disk or tape space copying the entire file in order to process
it.

Record-Out Sort (SORTR) 

The output from a Record-out sort is a file of complete records that are
immediately available for processing.  These sorted records can contain:

 *  Control fields and data.

 *  Control fields only.

 *  Data only.

A Record-out sort offers faster processing than the Address-out as well
as enabling you to reformat files and to create new files from
reformatted records.

Count-Only Sort (SORTC) 

This sort performs a Count-only pass on the input files.

Using a Count-only sort, XSORT can provide you with a statistical
analysis of the sort without actually performing the sort or producing an
output file.
