Example
The following example describes the help system.
Console#
help
Help may be requested at any point in a command by entering a question mark '?'. If nothing
matches the currently entered incomplete command, the help list is empty. This indicates
that for a query at this point, there is no command matching the current input. If the
request is within a command, enter backspace and erase the entered characters to a point
where the request results in a display.
Help is provided when:
1. There is a valid command and a help request is made for entering a parameter or argument
(e.g. 'show ?'). All possible parameters or arguments for the entered command are
displayed.
2. An abbreviated argument is entered and a help request is made for arguments matching the
input (e.g. 'show pr?').
