//JOB1     JOB   ,,MSGLEVEL=(1,1)
//STEP     EXEC  PGM=AION
//SYSIN    DD    *,DSID=(ABLE,V),VOLUME=SER=123456,
//           DCB=LRECL=80
//SYSPRINT DD    SYSOUT=E,DCB=LRECL=128,DSID=BAKER

In this example, the SYSIN DD statement indicates that the input is on diskette 123456 in data set ABLE and must have been verified. The output will be written on a diskette in data set BAKER.
