Hi Namshr,

COND - Each step sends an a return code to the system upon completion.
This is called condition code. COND parameter is used to control
the execution of subsequent job steps, depending on the condition
code that is returned for prior step.

Return code number between 0 and 4095

Syntax -> COND=(comparsion-code,condition)
(If coded on job)

COND=(comparsion-code,condition [,stepname] [,EVEN / ONLY])
(If coded on step)

condition can be GT,GE,LT,LE,EQ,NE

Example JCL -> COND coded on JOB

//MYJOB JOB (R475),'KRISHNA REDDY'
// COND=(4,GT)
//STEP1 EXEC PGM=COBPROG
//STEP2 EXEC PGM=COBPROG2

In this example we are specifing that if the number
4 is grater than the return code of STEP1, then STEP2
is to be bypassed. It is elaborated further in the
following image

COND coded on EXEC statement

//MYJOB JOB (U769),'KRISHNA REDDY'
//STEP1 EXEC PGM=PROG1
//STEP2 EXEC PGM=COBPROG,
// COND=(8,EQ,STEP1)
//

In this example the COND parameter is used to specify that
STEP2 should be by passed if 8 is equal to the return code
issued by STEP1.

In addition to Ekta,

COND parameter coded in JOB statement overrides the one in EXEC statement.

Ex:

//MYJOB JOB (U769),'KRISHNA REDDY'
// COND=(4,GT)
//STEP1 EXEC PGM=PROG1
//STEP2 EXEC PGM=COBPROG,
// COND=(8,EQ,STEP1)
//STEP3 EXEC PGM=PROG2,
// COND=(4,LE,STEP2)
//

If 4 is > the return code of step1, then STEP2 and STEP3 won't be executed. Else COND parameter in EXEC will be checked.

Thank U,
