I'd rather see a compiler-interpretable "way" of doing this. You could always just use your own for now, until something comes along (like how many #define N(a) there are in the tree, until nitems showed up.) Ie: #define A_UNUSED_T void (A_UNUSED_T) foo; That way (a) it's easy to change with a compile macro change, (b) if it ever clashes, it should be easy enough to rename without having to risk renaming fields you didn't want to, and (c) it's compiler-interpretable. I wonder if bde has any ideas on where a BSD "unused" hint could be stuffed.. Adrian
