RENAME command operands

old_name: specifies the name that you want to change. The name that you specify can be the name of an existing data set or the name of an existing member of a partitioned data set.
new_name: specifies the new name to be assigned to the existing data set or member. If you are renaming or assigning an alias to a member, you can supply only the member name and omit all other levels of qualification.
ALIAS: specifies the member name supplied for new_name operand is to become an alias for the member identified by the old_name operand.
You can rename several data sets by substituting an asterisk for a qualifier in the old_name and new_name operands. The system changes all data set names that match the old name except for the qualifier corresponding to the asterisk's position.

Note: Do not use the RENAME command to create an alias for a linkage editor created load module.
