uppercase and lowercase work apparently only on any-string. But it's too bad it doesn't work on character. You can do a string or a filename, but not a single character. You can write a lower-char function that converts the char to a string then do lowercase then convert back to char again, but it seems a bit wasteful and unnecessary. I submit that making these functions work on a char and return a char is a useful and reasonable thing. Comments? galt
