    Thanks a lot for the answer and the new version of FemView, I think the
    new utility wil be appreciate from all users.
    Working on it I' ve noticed that it would very useful have plot and
    txt files expressed all in the same coordinate system. I mean, a large
    number of application, in the magnetic field design, requieres, like
    shown in the femmplot window, the knoledge in the cartesian or polar
    system of both geometrical point coordinates and related fields ( flux
    density ,field intensity) Bx,By, Hx,Hy or the polar ones. I think that
    a development on this argument, in the next release of your code, shall
    be surely appreciate. At the moment I wonder if a simple transformation
    of i.e. Bn Bt data into Bx By is possible with enoutgh accuracy.
    Thank in advance for yor attention and comments if any.
    Bob
