RANGE

          REAL RANGE[2]

    Specify the range (in 3rd axis unit) of displayed  channels.  This  pro-
    vides  a facility similar to FIRST and LAST variables, but in a more us-
    er-oriented unit.

    RANGE should not be confused with SPAN, which  specifies  the  displayed
    velocity  range  when  one of the 2 first axis is of type Velocity, e.g.
    for SHOW PV
