Example of the DSID parameter
//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.
