    Thanks dw,
    The CelestialFix.exe program can load and save files with the extension .obs
    Now I am writing an interface between the AlmanqueNautico.exe and CelestialFix.exe
    I have attached the input file for CelestialFix.exe, for this exercise

    go to goole groups, and andres' message looks fine.
    andres, when using your programs, must the data be typed into each one
    as I work through them, or can I create files and pass the names
    somehow.  Very nice programs.  Good plots.  Thanks.
