I don't need them. I was just curious. I updated a script I had to try to exercise all possible number, character, identifier and string branches in a R6RS parser. I used it to examine the parsing differences between Guile-1.8.x, Guile-1.9.x, and MzScheme, which was rather amusing. The exact, complex number is partially implemented by MzScheme. Thanks, Mike
