I suppose I should have said "in most cases, it doesn't make a hill of beans to performance," but I thought that was clear from the context. You make a good point, but it rests on some assumptions that may or may not apply in OP's case. In particular, I don't see what error a simple constant string declaration is likely to catch, especially since the code in question does not, in fact, present any conditional logic. Still, TIMTOWTDI, and only OP knows at what point the benefits of constants outweigh the benefits of interpolation in his situation.
