Parameter type Keyword, optional Purpose Use the DSID parameter to specify the data set identifier of an input or output data set on a diskette of the 3540 Diskette Input/Output Unit. An input data set is read from a 3540 diskette by a diskette reader program, and an output data set is written on a 3540 diskette by a diskette writer, which is an external writer. To read a data set from a 3540 diskette, the DD statement must
contain:
To write a data set on a 3540 diskette, the DD statement must contain:
Also, a system command, from the operator or in the input stream, must start the diskette writer before this DD statement is processed. Note: The system ignores the DSID parameter
on a DD *, DD DATA, or a DD statement with the SYSOUT parameter, except
when a diskette reader or writer processes the JCL.
