Consistent, Easy-To-Use Interface to Cost-Reduced Panel

       Described is a way of handling cost-reduced panels that
have even less hardware features.  An operator panel of a computer
system provides a computer operator a wide variety of functions
through a fairly small set of operator interface hardware, a Hex
character display and a few control buttons.

      This cost reduced panel's hardware has a reduced display size
(half the normal size) and has removed the scroll-down function
leaving the following interface facilities:
-  Hex character LCD display (half normal panel size)
- Available panel operations:
      1.  Press scroll-up key
      2.  Press enter key

      To request a function that the operator panel provides, an
operator first selects the function by scrolling through the list to
a desired function number, and presses the enter key.

      Some of the functions also support subfunctions.  To request a
subfunction, the operator must first select a desired function number
and press enter.  If this function supports subfunctions, this places
the panel in subfunction mode.  Then the operator must scroll through
the list of subfunction until the desired subfunction number is
encountered, and press enter.  This requests the desired subfunction.

      Note that a normal panel has the scroll-down operation
provided, whereas the cost-reduced panel does not.  On the
cost-reduced panel, if the user selects a function that is lower than
the current function, he must scroll up to the maximum function and
allow the wrap around to bring it around to the minimum function, and
then scroll up to the desired function.

      To minimize this inconvenience to the user, the size of the
list is kept to a minimum by only including the functions and
subfunctions that apply to the given circumstances.  This list of
available functions/sub-functions must be supplied to the panel via
the panel control protocol.

      The panel takes advantage of this new information by only
scrolling through the number of subfunctions that are applicable to
this particular function.  For example, if a certain function
supports 20 subfunctions, the wrap around will occur after 20.
Without this infor mation, the panel is forced to scroll through the
entire list of 256 possible subfunctions before wrap around would
occur.

      For purpose of illustration, the display size of the normal
panel is assumed to be 16 hex characters, and 8 hex characters for
the cost- reduced panel.  And the information that is displayed on
the cost-reduced, as well as the normal, panel display is assumed to
be:  4 hex characters of information to indicate the selected
function/sub-function, 2 hex characters of information to indicate
the activation status of the function, and 8 hex characters of
information for the results from the requested function.  Because the
cost-reduced hardware display only supports 8 characters at a time...
