UUTEX1 is a user-written routine called by UUTIL before a function processor is called. The exit can be used to impose security restrictions on the use of certain UUTIL functions, over and above those already defined by Com-plete.

By default, certain functions of the UUTIL maintenance utility are only open to "Super Users". Control users can access "Super User" functions by either specifying the maintenance password when invoking UUTIL or, alternatively press PF10 on the UUTIL main menu. This prompts for the maintenance password and, when confirmed, will bring up an additional number of utilities usually restricted to the administrator.

How to Use UUTEX1

The first function of UUTEX1 (function code 0) allows the UUTEX1 user exit to override this password protection and allow a control user to automatically receive the full functionality when invoking UUTIL.

The second function of UUTEX1 (function code 4) allows the exit to control the use of the individual subfunctions of UUTIL shown on the right side of the UUT1 map.
