Explaining Example -

• SYSUT1 DD maps the input data set (MATEPK.IEBGENER.INPUTPS).
• SYSUT2 DD specifies the output file as PDS member MATEPK.IEBGENER.OUTPDS(BACKUPPS). MATEPK.IEBGENER.OUTPDS is an existing PDS and BACKUPPS is the newly created member in this job.
• SYSIN DD Specifies the control data set as DUMMY to identify no control statements are used.
