The proper way to do all this is with Mex, and lerfu can be mixed with PA in Mex strings. C Sharp is just cyza'u and double sharp is cyza'uza'u (me'i would be used for flats). (You could also use ma'u and ni'u as specified in the cmavo list for ji'i-based rounding). cyno would then work for C natural (octave numbers should use subscripts with xi, I think). lojbab -- lojbab lojbab@lojban.org Bob LeChevalier, President, The Logical Language Group, Inc. 2904 Beau Lane, Fairfax VA 22031-1303 USA 703-385-0273 Artificial language Loglan/Lojban: http://www.lojban.org
