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.

Learn about essential and most frequently used JCL statements and parameters, as well as coding techniques. JCL statements tell z/OS where to find the appropriate input, how to process that input (that is, what program or programs to run), and what to do with the resulting output.

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.

Job Control Language (JCL) is the command language of Multiple Virtual Storage (MVS), which is the commonly used Operating System in the IBM Mainframe computers. JCL identifies the program to be executed, the inputs that are required and location of the input/output and informs the Operating System through Job control Statements.

In most cases, It is a good practice to code the COND parameter at STEP Level but based on your requirement, you can code this at JOB level or STEP level or at both the places. Syntax: COND[.procstepname]=(rc,logical-operator) or COND[.procstepname]=(rc,logical-operator[,stepname][.procstepname]) or COND=EVEN or COND=ONLY

To correctly code JCL statements and parameter values, you need to collect certain company-specific information. Use this checklist and worksheet to document what you need to know about your company's IT environment.

Sample JCL that uses the Java batch program and environment script (Note: Sample includes the following steps): Encrypt a data set with a passphrase. Decrypt a data set with a passphrase.

JCL (Job Control Language) is a programming language used on IBM mainframe operating systems. JCL is a language with a set of predefined instructions that are used by the JOB ENTRY SUBSYSTEM (JES2 or JES3) to instruct the system on how to …

2022年9月30日 · Job Control Language (JCL) is a scripting language that describe jobs, to the Operating System that runs in the IBM large server (Mainframe) computers. JCL acts as an interface between your application programs (COBOL, PL/1 , …
