SET BLANKING

        [GREG1\]SET BLANKING Bval Eval

    Define a blanking value Bval with tolerance Eval. Default is no blanking
    (i.e.  Eval  negative). The blanking is used by most curve plotting com-
    mands such as CURVE, CONNECT, POINTS to ignore data points which  verify
    ABS(Y-Bval)  less  or equal to Eval. The blanking value is also used for
    contours (RGMAP), to avoid plotting contours in pixels whose value veri-
    fy  the  same  relation  as  above. And finally, some commands require a
    blanking value to attribute when they are unable to define a  real  val-
    ue ; this include RANDOM and MASK.
