Command Help
Cursor sensitive help can also be provided on AS/400 commands but it's not required. If help has been provided one can view help for a parameter by moving the cursor to the desired parameter field and pressing F1 (help). To get help for the entire command itself (and all of its parameters) the user would press F1 anywhere on the prompt display and then press F2 (extended help).
