Operation Notes
You use the HELP command to display information about MPE/iX in one of two ways: by
omitting command parameters to enter the Help subsystem or by getting information
about a single command from the colon prompt.
Using HELP as a subsystem
Enter the HELP command without specifying any parameters to invoke HELP as a
subsystem. You will see the first screen of Help, called HELPMENU. It lists the choices
available to you so that you can review the operation of Help and get a brief overview of
the changes found in the MPE/iX operating system.
Once you are in the Help Subsystem, you display information by entering the name of the
command, UDC, error message, variable, expression, function or other item that you want
at the greater-than (>) prompt. For example:
:HELP
>FINFO
