I'm not sure we addressed those in the coding conventions. I would like to say: 1) const references are always fine; 2) non-const references as local variables are always fine; 3) non-const references as function parameters should never be used without a really excellent reason. The reason is simply that using non-const references as function parameters means that arguments passed to a function can change without any indication, and that is potentially quite confusing. Adding an & before an output argument is easy enough, and we're all used to it. Ian
