It is a DD (Data definition) statement, and it specifies
where
the program (which is specified in EXEC statement)
exists.
It is applicable to all job steps in that job. It
cannot be used
in cataloged procedures.

Syntax -> //JOBLIB DD DSN=dataset

EXAMPLE JCL ->

//MYJOB JOB (E343),'KRISHNA'
//JOBLIB DD
DSN=SE.TEST.LOADLIB,DISP=SHR <--- Attention
//STEP1 EXEC PGM=COBPROG


Immediately following the JOB statement is
the JOBLIB DD
statement. This is used to specify the
location of the
program that is to be executed.
