CTG0808W CTGBATCH Dynamically allocating a JES LOG destination as STDOUT DD statement is missing or invalid
CTGBATCH was unable to use the supplied STDOUT DD statement, or the STDOUT DD statement was not defined.
CTGBATCH continues. A JES log will be dynamically defined for stdout log messages. The log name will likely be 'SYS00001'. When CTGBATCH completes, the JES return code will be at least 4.
If the JCL for CTGBATCH did contain a STDOUT DD statement, verify that the definition is correct.
