CTG0810W CTGBATCH STDENV DD statement missing or invalid, but CTGBATCH will attempt to continue
CTGBATCH was unable to use the supplied STDENV DD statement, or the STDENV DD statement was not defined.
CTGBATCH continues. If the target program is a USS executable (e.g. ctgmsgs) then a STDENV may not be required.
If the JCL for CTGBATCH did contain a STDENV DD statement, verify that the definition is correct.
