Paul Nevai asks for conversion routines between decimal and hex.  Here's
a subroutine to convert from hex to ascii.  Conversion from strings to
hex is about as simple.

	void
	hex_to_string(value, result)
	unsigned short	value;
	Str255		result;
	{
		int	i, v;
		result[0] = (sizeof value) * 2;	/* 8-bit bytes!		*/
		for (i = result[0]; i >= 1; --i) {
		    v = value & 0xF;
		    value >>= 4;
		    result[i] = (v <= 9) ? v + '0' : v + ('A' - 10);
		}
	}
