Notes about this Table

Re	Indicates a SAA/CUA reserved function key. In such cases the function key cannot be reassigned to another function key, even if the specified functions don't apply to a particular panel.
Op	Indicates a non-reserved SAA/CUA function key. In such cases the function key may be reassigned to other functions, but only if the application does not support the functions proscribed for the function key by this table.
*	Indicates an SAA/CUA function key assignment that is proscribed for complete SAA/CUA compatibility, but is not currently implemented directly within LANSA. The use of such keys is controlled by the USER_KEYS parameter of DISPLAY and REQUEST commands. It is the responsibility of the user to implement such key assignments in RDML programs as per the SAA/CUA guidelines described by the table above.
***	Indicates a non-SAA/CUA proscribed function key that is required in this table because it is implemented by LANSA.
