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 with-
out actually performing the sort or producing an output file.
Running the XSORT Program
The following figure illustrates how XSORT sorts your files.
Figure 1-3.
1 MPE statements are your job or session control commands to MPE XL.
1 Sort specifications include type of sort, sequence, record information, and instructions formatting
output.
2 File or files can be KSAM or sequential MPE (including non-disk files such as magnetic tape).
3 XSORT passes work records to be sorted to SORT which, in turn, sorts them in a work file. What-
ever work is required can then be performed without any disturbance to the input files.
4 Output files can contain:
