       /NAME=job-name

    Names the job (and possibly the batch job log file). The job name
    must be 1 to 39 alphanumeric characters. If characters other than
    alphanumeric characters, underscores (_),  or dollar signs ($)
    are used in the name, enclose the name in quotation marks (" ").
    The default job name is the name of the first file in the job.

    If you omit the /LOG_FILE qualifier, the job-name value must be
    a valid file name. The SHOW ENTRY and SHOW QUEUE/FULL commands
    display the job name.
