    if you end with a hyphen, you get a syntax error.  if you print a dot, it outputs a zero.  fun stuff!

    So we shan't signal messages that end in any of 'AJKMOQTUVWXY' 8-)

    it's tad more complicated than that. SOS does not output 6 zeros

    So it seems each leading hyphen will remove one following period, but if there are any following periods it will always output at least one zero no matter how many leading hyphens there are.
    hmm - no, these are not simple rules!
