Using the JES XCF exits and macros

This chapter provides a task-oriented approach to using the JES common coupling services to tailor the IBM-supplied services or create your own coupling processing. This chapter provides:

An overview of JES and JES XCF processing
An overview of available JES XCF exits and macros
An explanation of which JES environments can use the macros
The purpose of each exit and macro
An overview of component trace and diagnostic support.

The macros and the services they provide are intended for use within JES. Throughout this chapter and those following are recommendations to use specific macros in specific exits. The macros, can be placed directly within JES source code; however, IBM does not intend such use.

Refer to Coding the JES XCF exits and JES XCF macro reference for detailed information about coding the exits and macros.
