Explain the difference between the COND parameter and the IF statement in JCL.
- COND is used for job-level conditions, and IF is for steps
- COND is used for setting return code conditions
- IF is used for job-level conditions, and COND is for steps
- IF is used for setting conditions based on system variables
COND is used at the step level, while IF can be used at both job and step levels
What is the relationship between the COND parameter and the ELSE statement in JCL?
- COND parameter checks job syntax
- COND parameter controls job execution
- ELSE statement handles job dependencies
- ELSE statement specifies job steps
The COND parameter controls job execution based on condition codes
Which JCL statement is used to specify a condition to execute a job step?
- COND
- CONDITION
- EXECIF
- IF
The COND parameter is used to specify a condition for executing a job step in JCL
Conditional execution of job steps can be controlled using the _______ parameter in conjunction with the PEND statement.
- COND
- CONTROL
- ELSE
- IF
Conditional execution can be controlled using the COND parameter with the PEND statement.
The _______ parameter in JCL helps control the execution flow based on specific conditions.
- COND
- CONTROL
- EXECUTE
- PARM
The COND parameter in JCL helps control execution flow based on conditions
In JCL, which parameter is commonly used to define job dependencies?
- COND
- DEPEND
- EXEC
- JOB
The COND parameter is commonly used to define job dependencies in JCL
In JCL, the _______ statement can be used to specify the conditions for job dependencies.
- COND
- DEPEND
- JOBDEPEND
- WAIT
The COND statement is used to specify conditions for dependencies
You have a JCL job with two job steps, A and B. You want step B to execute only if step A completes with a return code of 0. How would you achieve this using JCL's conditional processing?
- COND parameter on step A with COND=(0,EQ)
- COND parameter on step A with COND=(0,NE)
- COND parameter on step B with COND=(0,EQ)
- COND parameter on step B with COND=(0,NE)
To execute step B based on the completion code of step A, you use the COND parameter with (0,EQ) to check if the return code is 0.
You have a JCL job with multiple steps. The third step should execute only if both the first and second steps execute successfully. How would you define this in JCL?
- COND parameter on STEP3 specifying (0,EQ,STEP1) and (0,EQ,STEP2)
- COND parameter on STEP3 specifying (0,GT,STEP1) and (0,GT,STEP2)
- COND parameter on STEP3 specifying (0,LT,STEP1) and (0,LT,STEP2)
- COND parameter on STEP3 specifying (0,NE,STEP1) and (0,NE,STEP2)
The COND parameter on STEP3 is set to execute only if both STEP1 and STEP2 complete with a return code of 0, indicating successful execution. This ensures the third step runs only when both preceding steps are successful.
A critical part of your JCL job depends on a specific dataset's existence. If the dataset is absent, you want to skip that part. How would you handle this scenario using JCL conditionals?
- COND parameter on the step specifying (0,EQ,
) - COND parameter on the step specifying (0,NE,
) - COND parameter on the step specifying (4,EQ,
) - COND parameter on the step specifying (4,NE,
)
Using the COND parameter with a condition of (0,NE,) allows the step to execute only if the specified dataset is present, ensuring the critical part of the job is skipped if the dataset is absent. This helps in handling scenarios where job execution depends on the existence of a specific dataset.
