The help viewer will automatically display the message text corresponding to the number when the user pressed the help key. By default, the help key is Ctrl-W in TUI mode and F1 in GUI mode.
Note that you can implement your own help viewer by overloading the SHOWHELP() function defined in FGLDIR/src/fglhelp.4gl. This allows you to customize the help system for your application.
