-Numbers are range-checked at point of usage. Signed byte values should be between \mono{\$80} (\mono{-128}) and \mono{\$FF} (\mono{+127}) inclusive, as these values are the extremes of what can be represented with signed 8-bit values. Unsigned byte values should be between \mono{0} and \mono{\$FF} (\mono{255}). Signed  word values should be between \mono{\$8000} (\mono{-32768}) and \mono{\$FFFF} (\mono{+32767}) as these are the extremes of signed 16-bit values. Unsigned word values should be between \mono{0} and \mono{\$FFFF} (\mono{65535}).

 Note that the assembler cannot tell the difference between the representation (in 8 and 16 bits) of signed/unsigned representation of negative and positive numbers, as they share the same bit patterns.
