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?').
