            [BUNDLES\]COMBINE OutCube CODE In1 In2 [Off] [/FACTOR A1 A2]
          [/THRESHOLD T1 T2] [/BLANKING Bval]

          CODE is the operation code. Allowed values are
        ADD      or PLUS    OutCube = A1*In1 + A2*In2 + Off
        SUBTRACT or MINUS   OutCube = A1*In1 - A2*In2 + Off
        DIVIDE   or OVER    OutCube = A1*In1 / A2*In2 + Off
        MULTIPLY or TIMES   OutCube = A1*In1 * A2*In2 + Off
        OPACITY             OutCube = -Log( A1*In1 / A2*In2 + Off)
        INDEX               OutCube = Log( A1*In1 / A2*In2) / Log(Nu1/Nu2)
        where Nu1 is the Frequency of In1, and Nu2 that of In2.  Off is 0 if not
        specified.

        Cube,  In1  and In2 are names of files or SIC Image variables, depending
        on whether a dot (.) is present in them or not.
