Relationship to other parameters
z/OS MVS JCL Reference
You can specify the following DD parameters with the DD * and DD DATA parameters. All other parameters are either ignored or result in a JCL error.
Restrictions when coding LRECL: If you code LRECL with the * parameter, you cannot submit a data set to JES3 with a record length greater than 80 bytes.
You cannot use the TSO/E SUBMIT command to submit a data set to JES2 or JES3 with a record length greater than 80 bytes.
Note: In-stream data within a cataloged procedure is also limited to 80 bytes.
You can submit a data set to JES2 or JES3 with a record length greater than 80 bytes by submitting the following JCL:
In this example, IBMUSER.LONGDATA.JCL contains the data with a record length greater than 80 bytes.
In a JES3 system, the record length limit is the size of the installation-defined spool buffer, minus 46. (For example, if the buffer size is 4084, the record length limit is 4038.) JES3 fails any job that exceeds this limit.
If the records longer than 80 bytes include JCL to be transmitted to a remote system using JES3 // XMIT or //*ROUTE XEQ, or JES2 /*ROUTE XEQ or /*XMIT with JES3 in the network, the records are truncated to 80 bytes.
For JES3 SNA RJP input:
For 3540 diskette input/output units: VOLUME=SER, BUFNO, and DSID on a DD * statement are ignored except when they are detected by a diskette reader as a request for an associated data set. See 3540 Programmer's Reference. On a DD * or DD DATA statement processed by a diskette reader, you can specify DSID and VOLUME=SER parameters to indicate that a diskette data set is to be merged into the input stream following the DD statement.
