DD Statement Restrictions

The following DD statement keywords have no effect or function inconsistently in the APPC scheduling environment:

Keyword: Description
*: Specifies in-stream data to follow
DATA: Specifies in-stream data to follow
DLM: Specifies the delimiter to terminate in-stream data
TERM=TS: Dataset represents Input/Output with a TSO terminal
SUBSYS: Symbolic substitution is inconsistent when you code &SYSUID as a subparameter.

Note:

Even though these keywords have no effect, if found within the JCL, they must be syntactically correct to avoid a JCL error.
Instream DD * or DD DATA statements are processed as JCL statements and could cause JCL errors. The /* statement (with a blank as the third character) is ignored.
