DDname is missing or is DD DUMMY – use is ignored
Explanation
A command was entered using a DDNAME operand. However,
the DD statement definition was not in the JCL stream. Execution proceeds,
but could terminate at a later point if the DDNAME is for an input
file or a required output file.
System action
Processing continues, but the report requiring this
DDname might fail.
User response
Check for a spelling error on the DDNAME or OUTPUT
operand, or supply the missing JCL statements, then resubmit the job.
