SET MATCH

        LAS\SET MATCH [Tolerance [Unit]]

    Turn  on the checking of position-matching in CONSISTENCY (and the other
    commands using it). This tolerance is also used in FIND, MAP and  a  few
    other commands.

    The  Tolerance  is  the offset position tolerance expressed in the given
    unit if any (RAD, DEG, MIN, SEC, MAS), or current Class unit  if  absent
    (current  SET  ANGLE).  If the Tolerance is absent, it resets to its de-
    fault (2 arc seconds).
