	this function converts a value
	to make it emulate a char
	(256 max characters)

	it can emulate signed and
	unsigned chars. the value
	will not go beyond 0-255
	if unsigned, and if signed
	the values will remain at -128
	to 128.

	tochar returns a signed char
	and touchar returns an unsigned
	char.
