What is the significance of using set Maxcc 0 command in a JCL step?
What is the significance of using set Maxcc 0 command in a JCL step?
In the same control card, after deletion step if we use IF & Set MAXCC=0, it will set that return RC as 0.
What is return code in COBOL?
The RETURN-CODE special register can be used to pass a return code to the calling program or operating system when the current COBOL program ends. When a COBOL program ends: If control returns to a calling program, the value of the RETURN-CODE special register is passed to the calling program. …
How do you bypass a step 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. This COND parameter can also be used to skip a step based on the return code from a previous step or steps in PROC.
What is return in program?
In programming, return is a statement that instructs a program to leave the subroutine and go back to the return address. The return address is located where the subroutine was called. In the example JavaScript below, the function returns to the code that called it if the number sent is less than one.
How can we skip a step in JCL with Cond?
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….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 do you execute only odd steps in JCL?
I need to execute only odd or even number steps witout condition code? You can do this only by coding COND=(99,NE) in all the even or odd step to prevent it from executing. Alternatively you can have all the even step in one proc and odd step in another proc and one COND parameter and skip the steps.
What is DCB in JCL?
DCB. The Data Control Block (DCB) parameter details the physical characteristics of a dataset. This parameter is required for datasets that are newly created in the job step. LRECL is the length of each record held within the dataset. RECFM is the record format of the dataset.
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).
How do I perform conditional processing in a JCL?
The Job Entry System uses two approaches to perform conditional processing in a JCL. When a job completes, a return code is set based on the status of execution. The return code can be a number between 0 (successful execution) to 4095 (non-zero shows error condition).
What is the basic syntax of a JCL COND parameter?
Following is the basic syntax of a JCL COND Parameter: COND= (rc,logical-operator) or (rc,logical-operator,stepname) or COND=EVEN or COND=ONLY One return code test is: (code,operator). You can omit the outer parentheses if you code only one return code test or only EVEN or ONLY. Specify up to eight return code tests.
What is the return code for a job?
When a job completes, a return code is set based on the status of execution. The return code can be a number between 0 (successful execution) to 4095 (non-zero shows error condition). The most common conventional values are: 4 = Warning – minor errors or problems. 8 = Error – significant errors or problems.
