    Re: UTM to lat/lon formulas

    The algorithm should be readable from the Pascal source. After all,
    human readers were the original target for Pascal.  :-)
    Once you know the algorithm, you should be able to make a spreadsheet
    macro to do it, on whatever spreadsheet you may have.
    I know that when my wife resolved to try doing sun sights on a passage
    from Nova Scotia, she took the formulas from the Nautical Almanac and
    put them into Lotus 123 (remember that?). That was before laptops had
    hard disks, so the program was on one floppy, the data on the other.
