PDM supports user-defined options but it doesn't use UIM.  PDM is built 
with normal display file support using subfiles and multiple record 
formats.  If PDM can do it then you can too!

You cannot add your own functions to IBM panels because they haven't been 
designed to support that.  They could, of course, but I don't see 
Rochester doing that -- especially with their current love-affair with 
Windoze as the AS/400 user interface.  (Excuse me while I throw up.)

It is certainly possible to support user-defined options using UIM if you 
take responsibility for processing the list actions in your application.  
A select list could be used to check for predefined options (e.g., any 
numeric options) and then call a program to handle user-defined options 
(e.g., alphabetic options).  A generic list processor could be created 
that looked for options in a file, performed variable substitution, and 
ran the resulting command.  The real difficulty is handling options that 
make no sense for certain lists e.g., a RunProgram (RP) option invoked on 
a WRKSPLF panel.  I might attempt that in the final chapter of the book 
but maybe that should be left as an exercise for the reader :)

Simon Coulter.
