Yes, LanX, and in scalar context it returns the NUMBER of patterns that matched. That's what I'm using in my (much larger) script.

That's exactly what I'm doing, davido.
Obviously, if I posted a (much larger) block of real-life code here, it would make more sense (to those who bother comprehending it), but there would be much fewer interested people. A short, distilled version of the problem may not make real-life sense, but is much easier to discuss.
