JCL U

Description 

This command executes a "user exit" from a jCL  program. It takes the general form: 

Unxxx

 Where: 

  • n represents the user exit entry point
  • xxx is the id of the user exit.


Note: 

User exits are user written functions, which are used to manipulate buffers and perform tasks beyond the scope of the standard jCL  commands.

See the Time and Date topic and the TR command for more examples of "standard" user exits.
