SORT-MERGE/XL allows you to sort files by single or multiple
key fields and to merge two or more sorted files into a single new sorted file.
You may use SORT-MERGE/XL as a standalone utility (either
interactively or in batch mode), or from within a program. For information on
how to use SORT-MERGE/XL programmatically, refer to the
SORT-MERGE/XL Programmer's Guide.
