# Description

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

Unxxx
1

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.

# Example 1

# Example 3
