The following pushbuttons are located at the bottom of the appropriate
     displays:

     OK -       After you are finished making changes in a display, push OK
                to approve the action.  The appropriate NCL commands will be
                issued, and the current display will be dismissed.

     APPLY -    Does the same thing as the OK pushbutton, but the display
                remains up after the NCL commands have been issued.  This is
                convenient because you can "try out" different settings by
                APPLYing them.  Since the display remains up, you can then
                RESET to the previous values or set the values to their
                DEFAULTs and re-APPLY if you like.  The display will remain
                up until you push CANCEL to dismiss the window.

     RESET -    Returns the values of all attributes back to what they were
                when you first entered the display.  These values are changed
                in the display only -- no NCL commands are issued until you
                push APPLY or OK.  The display remains up for further
                modifications until you push OK or CANCEL.

     DEFAULTS - Sets the values of all attributes to their defaults.  These
                values are changed in the display only -- no NCL commands are
                issued until you push APPLY or OK.  The display remains for
                further modifications until you push OK or CANCEL.

     CANCEL -   Push to abort the action.  The window is dismissed and no
                NCL commands are issued.

     CONTINUE - After all required arguments have been supplied, push to
                approve the action.  The appropriate NCL commands will be
                issued, and the current display will be dismissed.
