Using IBM-supplied cataloged procedures

A cataloged procedure is a set of job control statements that are stored in a system library (for example SYS1.PROCLIB). The storage location for cataloged procedures is installation-defined and might differ at your location from what is shown here.

Within a cataloged procedure, there are typically one or more EXEC statements, each of which can be followed by one or more DD statements. You can retrieve a cataloged procedure from the library by using its member name in an EXEC statement of a job control statement in the input stream.

Cataloged procedures can contain statements for the processing of an entire job, or statements to process one or more steps of a job, with the remaining steps defined in job control statements in the input stream. A job can use several cataloged procedures to process one or more of the job steps, or it can use the same cataloged procedure in more than one job step.

You can use cataloged procedures to save time and reduce JCL errors. If the statements in the procedure do not match your requirements exactly, you can easily modify them or add new statements for the duration of a job.

The cataloged procedures shown in this section are intended for use as references and do not necessarily reflect the procedures as they are provided at your installation. If options are not explicitly supplied with the procedure, default options established at the installation apply. You can override these default options by using an EXEC statement that includes the desired options (see Overriding and adding to EXEC statements).
