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?').
