Defaults

If you do not code the DD CHARS parameter, JES uses the following, in order:
  1. The CHARS parameter on an OUTPUT JCL statement, if referenced by the DD statement.
  2. The DD UCS parameter value, if coded.
  3. The UCS parameter on an OUTPUT JCL statement, if referenced.

If no character-arrangement table is specified on the DD or OUTPUT JCL statements, JES uses an installation default specified at initialization.
