Creating user exits through the User Exits Workbench
As an alternative to creating user exits manually, you can create, edit, compile, and link-edit a number of user exits through the User Exits Workbench tool. The tool enables you to customize your user exits by using the IBM z/OS Metal C language (for details about this language, see the IBM z/OS Metal C Programming Guide and Reference).
For a list of the exits that you can create through the User Exits Workbench, see HCL Workload Automation for Z exits supported by the User Exits Workbench
