//FILEOUT DD DSNAME=&SYSTEM..&DEPT..DATA,DISP=
(NEW,CATLG,DELETE),
// AVGREC=U,SPACE=(80,(100,20),RLSE),

Answer / abha
Example: If symbolic parameter is defined as CLASS=H
and later on in JCL we use SYSOUT=&&CLASS
At runtime SYSOUT=&&CLASS will be relaced by SYSOUT=H.
Hence here we have used CLASS as a symbolic paramter and
its usage is to increase maintainability because if later
we need to change the class it can be changed just at one
place instead of changing it at all the palces of it's
usage.

What is Automatic Restart ? EXEC PGM = PROG1, RD = R (Is it the Restart of a JOBSTEP or Restarting the execution of the program?) Do we Restart it or it automatically Restarts executing again and again ? Then when it will finish executing ? or After Abending, when we submit it again, then it is Restarted from the Last successful Checkpoint ? If some JOBSTEP is abending, what is the benifit to Restart it, WILL IT NOT ABEND AGAIN if you don't change the LOGIC ?
