Thanks.

Really? The three functions (gcd,lcm,chinese) according to the
documentation require at least one argument, but the rest are
optional. Therefore, I would expect that giving only one argument
would be valid. It seems this is not currently the case. In my
actual application, I accidently only gave one argument by mistake.
In any case, replacing "associative" with "associative (gcd,lcm,
chinese)" would be a small step towards helpfulness. Shalom, Michael
