BOX /BRIEF

        The  options /BRIEF and /NOBRIEF can be used to override the default
    tick labeling as ruled by the command G\SET AXIS. If /BRIEF is used, the
    tick  labels  are  abbreviated, if possible. If /NOBRIEF is present, the
    tick labels are kept entire.

    If the keyword X or Y is used as argument of the options,  it  indicates
    to apply the corresponding mode only to the designated axis.

    The  options /BRIEF and /NOBRIEF are compatible as long as the same axis
    is not designated twice. See HELP G\SET AXIS for details and examples.
