The SAME SORT-MERGE AREA clause optimizes the storage area assignment to a given
SORT or MERGE statement.
The SAME SORT-MERGE AREA clause is syntax checked, but is treated as documentation.

Notes:
- Syntax-checked only.
When the SAME SORT-MERGE AREA clause is specified, at least one file-name
specified must be a sort or merge file. Files that are not sort or merge files
may also be specified. The following rules apply:
- More than one SAME SORT-MERGE AREA clause may be specified. However, a
given sort or merge file must not be named in more than one such clause.
- If a file that is not a sort or merge file is named in both a SAME AREA
clause and in one or more SAME SORT-MERGE AREA clauses, all the files in the
SAME AREA clause must also appear in that SAME SORT-MERGE AREA clause.
- Files named in a SAME SORT-MERGE AREA clause need not have the same organization
or access.
- Files named in a SAME SORT-MERGE AREA clause that are not sort or merge
files do not share storage with each other unless the user names them in a
SAME RECORD AREA clause.
