Rules for Writing the User-Exit Program

Control Blocks and Sample User-Exit Programs

Sample User-Exit Program for Schema and/or Subschema Compilers

Overview

This appendix presents the procedures for coding a user-exit program, which is called by the schema compiler and subschema compiler to:

• Perform security checks
• Enforce entity-occurrence naming conventions
• Maintain an audit trail of dictionary activity

A common user-exit program can be coded to be shared by the schema compiler and subschema compiler, or a specialized user-exit program can be coded for each or for only one of the compilers.

The rules and procedures governing the user-exit program are the same for all compilers that use it.
