What is condition code in JCL?
A COND parameter can be coded in the JOB or EXEC statement of JCL. It is a test on the return code of the preceding job steps. If the test is evaluated to be true, the current job step execution is bypassed. Bypassing is just omission of the job step and not an abnormal termination.
What is conditional parameter in JCL?
Condition parameter is used to decide execution of the JOB step based on the return code. And also COND parameter used to specify the return code validation the system uses to determine whether a job step will continue processing or not. COND parameter can be coded at JOB level and Step level.
What is the difference between cond even and only?
– EVEN & ONLY are the special parameters which are applicable to Step level. – COND=EVEN is to tell the SYSTEM that to execute that step even though any of the previous steps abnormally terminated. in case of Abends. The difference Between EVEN and ONLY is, Even executes irrespective of the previous steps return codes.
What is return code JCL?
Return code is set based on the status of execution of a job. The return code can be a number between 0 (successful execution) to 4095 (non-zero shows error condition). 4 = Warning – minor errors or problems.
What is Cond only in JCL?
JCL COND=ONLY If you want to execute a particular step only and only if any of the previous steps have Abended, then you should use – COND=ONLY in that step.
What would happen if cond parameter is present on both job and EXEC statement?
The COND parameter on both the JOB and EXEC statements is useful to set some conditions for all steps in the job and other conditions for particular steps. No COND parameters on JOB or EXEC statements means the system does not perform any return code tests, but tries to execute each step in the job.
What is PARM parameter in JCL?
PARM parameter is an optional keyword parameter in JCL. PARM parameter is a way to pass a data from JCL to the program but the maximum amount of data which we can send to the program using the PARM Parameter is 100 character. Syntax: PARM=DATA.
How can we skip a step using cond in JCL?
COND parameter is JCL can be used to skip a step based on the return code from the previous step or steps of the JCL. 2….Let us take some examples-
| Types | Condition example | Explanation |
|---|---|---|
| Type 1 | COND=(0,EQ) | Is return code 0 equals the return code from the previous step? If this condition is true then bypass this step. |
How pass data from Cobol to JCL?
- From JCL we can pass data into COBOL program two ways.
- One is through PARM (maximum limit is 100 bytes), second through Input file, third through SYSIN card.
What is the use of temporary dataset in JCL?
Temporary datasets need storage only for the job duration and are deleted at job completion. Such datasets are represented as DSN=&name or simply without a DSN specified. If a temporary dataset created by a job step is to be used in the next job step, then it is referenced as DSN=*.
What is S222 Abend in JCL?
Re: Space issue(ABEND S222) It is possible that there is not sufficient space and because of this the operator canceled the job. Post your JCL and control statements from the step that failed along with any informational/diagnostic info generated by the problem step.
What is Joblib and Steplib in JCL?
1. JOBLIB is defined at the start of the job before any EXEC and contains the load libraries to be searched for the entire job. STEPLIB is defined after an EXEC and applies only to that step. It also contains the load libraries to be searched for the step.
What is return code in JCL cond?
COND Parameter use Return Code in JCL COND parameter is used to test return codes from previous job steps and determine whether to bypass or execute specified job step. Return code is set based on the status of execution of a job. The return code can be a number between 0 (successful execution) to 4095 (non-zero shows error condition).
What is the use of Cond in JCL?
With the COND parameter, you can also run a step only and only if any of the previous steps have Abended. The ‘COND’ parameter defines the conditional processing in JCL and this is an important parameter in JCL. JOB level – In JOB Statement (JOB card). STEP level – In EXEC statement.
What is JCL cond bypassing?
If the test is evaluated to be true, the current job step execution is bypassed. Bypassing is just omission of the job step and not an abnormal termination. There can be at most eight conditions combined in a single test. Following is the basic syntax of a JCL COND Parameter:
What is the maximum number of Cond parameters in JCL?
Note: There can be multiple COND Parameter in JCL but a maximum of 8 COND parameter is allowed. COND parameter can be used at JOB level or STEP level or at both the places.
