//MYJOB JOB(P,U202,SH1),'FRANK SMITH',CLASS=A
//STEP1 EXEC PGM=PROGRAM1,SYSTEM=PROD,DEPT=INV,TYPE=DATA
//FILEIN DD DSNAME=&SYSTEM..&DEPT..&TYPE,DISP=SHR
//FILEOUT DD DSNAME=&SYSTEM..&DEPT..DATA,DISP=
(NEW,CATLG,DELETE),
// AVGREC=U,SPACE=(80,(100,20),RLSE),
// DCB=(LRECL=80,RECFM=FB)

A.Referring to the above coding, what is the effective
dataset name for the data definition FILEOUT?

PROD.INV.DATA

Here we are referring the symbolic variable with single &
Ampersand.

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.

COND -> step1 . . step2, Step2, Executes if the CC of step1 is 0. But even if it is NOT 0 and if we dont give COND, will step2 be executed ?
