Joaquin, Mark, Thanks for your replies. An exception would work in this case because there is no return value, however there might be problems with resource leaks - even if version 1_30_0 doesn't leak, a later one might. If I need a quick fix I might try it - but I think a safe, clean solution will involve a small change to the algorithm - unless there is a good trick that works with visitors. Richard
