Even a blind hog finds an acorn from time to time :)

Yeah, but what to subclass? The menu items are just structs with
no methods...

Someday. To quote the poll, "I like stability."

Drifting off topic ... if you *always* put the "const" immediately
to the right of the thing that's constant, you *never* get
confused, no matter how consts there are. I really
dislike the fact that "const blahblah" is a special case
that means exactly the same thing as "blahblah const."

Sure. This was just a knockoff for posting quickly.

Yup.

Not exactly, but the file list is fixed, it's not a directory lookup.
Thanks for looking into this Ian. It's had me stumped for days
and I must say I'm no further along. Which is a bit odd, since
I'd have thought this would be a fairly common thing to want to do.
Best,
Stan
