Talking about the Mill output. And I tend to agree with the answer of 6, mainly because you should be able to write out any modulus equation of a mod b = c as: b * x + c = a Where a, b, c, and x are integers, and b and c are positive. This would give: 10 * -1 + 6 = -4 representing -4 mod 10 = 6 -- -----Iammars www.jmcteague.com
