Place a null statement (1) at the end of a job’s control statements and data and (2) at the end of an input stream.

The system can also recognize the end of a job when it reads the next JOB statement or when the input stream contains no more records.

A null statement that does not end an input stream should be immediately followed by a JOB statement. The system ignores statements between a null statement and the next valid JOB statement.

Note: JES2 ignores a NULL statement when it is included in a job’s JCL statements. JES2 processes JES2 control statements following a NULL statement as part of the job (until the next JOB statement or EOF).

If a null statement follows a control statement that is being continued, the system treats the null statement as a blank comment field and assumes that the control statement contains no other parameters.
