Using registers as a "transfer medium" between the main (yes, even assmbler code has a main - whatever it is called) will, very likely, get you caught some day. Little shortcuts "just for test" has a way of sneaking their way into a final code and then may, some day, bite you in your lagest muscle. Erik |
