A HELP facility is a help catalog and the user interface to that 
catalog.  You create your own HELP facility by developing a help 
catalog and allowing users to access it via the MPE/iX HELP user 
interface.  You are probably already familiar with the MPE/iX HELP 
user interface; you use it when you access the MPE/iX HELP facility. 
HELP facilities provide extra information to the user by outputting 
explanatory text in response to keyword input. 
You create this information easily and access it in a 
simple and consistent manner. 
To create your own HELP facility, you first create a source file that 
contains keywords to identify sections of the catalog.  These keywords 
allow the user access to the HELP facility.  The source file is then 
formatted and the user interface is redirected to the formatted file. 
Finally, users access the HELP facility.
