Alas, far too modern for the VMS, but in Eco's book I find an interesting
reference to Leibniz and his "Lingua Generalis".
In 1678 he proposed a decomposition scheme whereby concepts would be
decomposed into more simple ideas. Then these primary ideas would be
numbered and every number would be encoded into a pronounceable word like
this:
1 2 3 4 5 6 7 8 9 = b c d f g h l m n
10^0 10^1 10^2 10^3 10^4 = a e i o u
Then the number 81.374 would be encoded like "Mubodilefa". But since the
vowels have a fixed meaning in powers of ten, the same number could be
expressed as "Bodifalemu".
