James Anderson James Anderson Thanks for your response. Have a question here.. Please clarify of lemme know if i missed something..

SYSOUT system defined dd name used for file status codes and system abend codes information and output of the display statement can be viewd and sysout parameter used to direct the output device and genarete during execution of the job to an output device SYSPRINT contains the compiled source listing and for each line in the soucrce listing a line number and offset no can be genarated.

There are certain symbols called system symbols , which are used for logon job executions. When the procedure is separated out from the JCL and coded in a different data store, it is called a Cataloged Procedure.

A PROC statement is not mandatory to be coded in a cataloged procedure. Calling a procedure from within a procedure is called a nested procedure. Procedures can be nested up to 15 levels. The nesting can be completely in-stream or cataloged. We cannot code an instream procedure within a cataloged procedure. 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 non-zero shows error condition.

The most common conventional values are:. 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. There can be at most eight conditions combined in a single test. When the condition is true at any particular job step, it is bypassed along with the job steps following it.

Following is an example:. When COND is coded in EXEC statement of a job step and found to be true, only that job step is bypassed, and execution is continued from next job step.

This gives more flexibility and user-friendly way of conditional processing. If it is 0, then STP02 is executed. Else, the processing goes to the next IF statement IF2. In ELSE, there are no statements. Else STP07 is executed. The IF-THEN-ELSE will not be executed in the case of abnormal termination of the job such as user cancelling the job, job time expiry or a dataset is backward referenced to a step that is bypassed.

If there is a requirement to do automated restart for specific abend codes only, then it can be specified in the SCHEDxx member of the IBM system parmlib library. In the above example, chk5 is the checkid, i. If there is more than one dataset of the same format, they can be concatenated and passed as an input to the program in a single DD name.

In a standardised JCL, the program to be executed and its related datasets are placed within a cataloged procedure, which is called in the JCL. Usually, for testing purposes or for an incident fix, there might be a need to use different datasets other than the ones specified in the cataloged procedure. In that case, the dataset in the procedure can be overridden in the JCL.

Please note that the dataset is referred as STEP1. GV00 and so on. GDG 0 , previous versions are referred as -1 , -2 and so on. An initial model DCB can be defined to be used by all versions, but it can be overridden when creating new versions.

GDG is deleted. Hence, the dataset is deleted when the job completes execution. If any of the GDG versions are set with an expiration date which is yet to expire, then those are not deleted and hence the GDG base is retained.

GDG is created as the output. GV00, then it leads to changing the JCL every time before execution. Any batch program executed through a JCL requires data input, which is processed and an output is created. There are different methods of feeding input to the program and writing output received from a JCL. In batch mode, there is no user interaction required but input and output devices and required organisation are defined in JCL and submitted. There are various ways to feed the data to a program using JCL and these methods have been explained below:.

The data is provided within the JCL. Two records of data are passed to the program. It is referred as IN1 within the program.

But the entire job log cannot be captured through this way i. The JCL uses the load module and not the actual program at the time of execution. Some corporate companies use Change Management tools like Endevor , which compiles and stores every version of the program. This is useful in tracking the changes made to the program.

The compiler options are passed using PARM parameter. INPUT and produces two output files written to the spool. In the above example:. The file can be opened, read and closed in the program. Utility programs are pre-written programs, widely used in mainframes by system programmers and application developers to achieve day-to-day requirements, organising and maintaining data.

A few of them are listed below with their functionality:. No operation utility. Used to return control to user and terminate. It is usually used to create empty dataset or delete an existing dataset. These utility programs need to be used with appropriate DD statements in a JCL in order to achieve the specified functionality. Usually, this is not recommended in view of performance for large files.

Input and output datasets can be defined using user defined DD names. It can compare two or more files on specified field s and create one or more output files like file with matching records, file with non-matching records, etc. A File can be split into n files based on a specified condition.

For example, a file containing names of employees can be split into 26 files, each containing the names starting with A, B, C and so on. It gives best utilization of system resources and efficient operation in bit and bit address spaces. Frequently used sort tricks using these utilities are explained in the next chapter.
