Formats for requesting deferred restart

The formats for the RESTART parameter of the JOB statement and the SYSCHK DD statements are as shown below.


//jobname  JOB MSGLEVEL=1,RESTART=(request[,checkid])
//SYSCHK   DD  DSNAME=data-set-name,
//             DISP=OLD[,UNIT=device-type,
//             VOLUME=SER=volser]
MSGLEVEL=1 (or MSGLEVEL=(1,y))
MSGLEVEL is required.
RESTART=(request,[checkid])
