Hello,

    I am trying to query the object length of line layer that fall within
    a region layer. The query appears to work, but when I try and verify
    the total length, I do arrive at the same answer as MapInfo.

    The lines may extend outside the boundary of one into another region.
    If I clip the lines at the each regions boundary, both MapInfo and I
    arrive at the same length.

    Could someone explain what MI is computing.

    TIA

    Peter
