As you should be. Plain old "char" *is* either signed or unsigned depending on your choice of compiler. And in effort to build code that runs as expected better compilers have a compile time switch to control code generation when the signedness is specifically indicated. See -funsigned-char, -fsigned-char, and -fno-unsigned-char in the avr-gcc man page. So in short plain old "char" is only being sloppy in not explicitly stating signed or unsigned. -- David Kelly N4HHE, dke...@hiwaay.net ======================================================================== Whom computers would destroy, they must first drive mad. _______________________________________________ AVR-GCC-list mailing list AVR-GCC-list@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-gcc-list
