MF_ALIAS

Specifies program aliases. Each set (pair) is 16 characters long - 8 characters for the program-name, and 8 characters for the alias. You can specify up to 10 pairs. This list is searched first and thus can potentially override the built-in list. If not found, the built-in alias table is searched.
Note:

You can alias any program other than IEFBR14, which is always processed as IEFBR14.

Syntax:

MF_ALIAS=program-name1 alias1 [program-name2 alias2] ...[program-name10 alias10]

Comments:

An entry shorter than 8 characters must have trailing spaces extending its length to 8 characters.

Example:

MF_ALIAS=IKJEFT1BIDAEFT01MYPROG  THEIRPRG

adds:
