RESULT CODES
    Result codes are displayed in either numeric or verbal code after the
command line is executed.
    Command Q determines whether the result codes will be displayed.  When
Q1 is selected, the result codes will be displayed.  When Q0 is selected,
you can see the codes on the screen.  Command V selects numeric (V0) or
verbal (V1) codes.
    The default values of these controls are fixed by DIP switches.  For
example, when DIP Switch 4 is set to N, the result codes do not appear on
the screen unless Q0 is entered from the keyboard.  (Refer to Chapter 1,
DIP SWITCHES).
