Ouch, I got sloppy looking at the types; been away from Perl a bit too long and forgot just how messy the IO space is these days.

I'm sure this and the other details provided by later responses will be enough to resolve this (but I'll confirm that when I've actually resolved it).

Thanks to you and everybody else; all the responses are useful, and I don't recall that any two have completely identical utility even!
