Actually no, I used to do a bit of 6502 assembler and used stuff like that
all the time. If the compiler would choke on it then ok but as far as an
operation it sure looks like the way I used to do things.

Well there is no string, so it could be handled as char and I don't see why
you can't do an xor on a character, I mean it seems to me that *should* be
a valid operation.

Are you saying there is a structure for a string type variable? We learned
that only way to do a string was with an array of characters.
