JCL statements are coded in 80 bytes. 72 of the 80 columns are available to code JCL. Last 8 columns are reserved for an optional sequence number. Each JCL statement is divided into several fields. Let's us see each field in detail, 1. Identifier Field: The identifier field identifies a record as a JCL statement.

LINES parameter is used to specify the maximum output lines to be printed on SYSOUT datasets. The line values are always multiples of 1000. For example - If the LINES=20 means, the maximum limit is 20000 lines. It also specifies the action to be taken when the lines exceed the coded limit. It is a keyword parameter and optional.

JCL (Job Control Language) is a programming language used on IBM mainframe operating systems. It is a language with a set of predefined instructions that are us

Specify the action that the system is to take if the maximum is exceeded. You can indicate that the job is to be cancelled with or without a dump, or that the job is to continue and the system is to notify the operator that the maximum was exceeded.

In this example, the job JOB1 will be cancelled when its output exceeds 500 thousand lines. The system will not produce a storage dump. Allowed to continue, with a warning message issued to the operator.

Job Control Language (JCL) is a scripting language used on IBM mainframe operating systems to instruct the system on how to run a batch job or start a subsystem. [1] The purpose of JCL is to say which programs to run, using which files or devices [2] for input or output, and at times to also indicate under what conditions to skip a step ...

After completing the JCL tutorial, you will be able to: Explain the basics of JCL. Identify statements and parameters in JCL. Define JCL Procedures, Symbols and others. Describe the significance of GDG. Explain JCL for batch applications. Explain IBM utility concepts. Implement the utilities for basic operations.

Example 1 shows continuation of a DD statement. The DD statement is continued from the first card image to the second card image. The comma on the first line indicates that continuation is expected.

Example 2: Input file has one or more records for same employee number. Write unique records to output. SORT FIELDS=(1,15,ZD,A) SUM FIELDS=NONE removes duplicates on fields specified in SORT FIELDS. In the above example, employee number is in the field position 1,15.
