1) The COND specifies condition for execution of subsequent job step depend on the return code from previous steps.
2) COND Can be coded in both JOB and EXEC statements. But COND written in EXEC stmt overrides on COND written in JOB stmt.
3) MAximum 8 conditions can be coded in the COND parameter. In case of multiple conditions if ANY of the condition is found TRUE then the JOB stops proceeding further.
4)It bypasses the step if the condition is true.

SYNTAX : COND=(CODE,OPERATOR,STEPNAME)
code can be 0 to 4095
Operator can be GT, LT, GE, LE, EQ
Stepname is optional,if omitted then the reurn code of all the steps are checked.

In EXEC you may find like

COND=ONLY it allows step execution if any prior step is ABENDED
COND=EVEN it allows step execution even if the prior step is ABENDED

Example.
//STEP2 EXEC PGM=PROG12,COND=(4,GT,STEP1)

Here system bypasses the STEP2 if 4 is greater than the return code from STEP1
