OK, here is another interface dilemma. I screwed up
before by not thinking as clearly as I should have about
what I was doing. (I'm certain this doesn't happen to you.)

So, out of 44 indices, I should have reserved 8 and 10 for
what the user expects them to be. I didn't. So now I want
to reserve them. This means I either (1) map this functionality
to unused index numbers, say 45 and 46, which REALLY defeats
the user's expectation, or (2) map these to what the user
expects but change the old numbers out from under all the
thousands of users (I'm being facetious) that have already
downloaded SYMCAT.

I've chosen option 2. I've thought hard about it. I don't
like it. But that's what I've done. Mostly this decision
stems from a GREAT reluctance to change an already-defined
interface, and from a bet that not too many people have
already downloaded and are using SYMCAT in their programs.
I could be completely wrong, but that's how these kinds
of decisions get made, for better or worse. :-)

Cheers,

David
