"char*" is a pointer to an arbitrary number of bytes. Str255 is an array of
256 bytes with a length byte at the beginning (hence Str255). You can use a
Str255 as a char* with typecasting, but you must remember to begin the reference
to the char-data at myStr255[1]: "*((char *)myStr255+1)" or somesuch (allowing
for bad parenthesis usage).
