Righto - that makes some sort of sense.

That seems likely; I had an early exit because the TeX format wasn't big
enough the first time round.

Righto; it'd help if you could say a little something about what it does,
so I can have a play with it and attempt to document it.

Quite possibly; I've just done a fontinst run with all the previously
generated files cleared out of the way and asking for this only:

\latinfamily{pck9}{}% Caslon Book BE; old style numerals

And I've got a set of vfs most of which have oldstyle numerals in them.
The one exception is the small caps founts: they have `missing glyph'
blocks instead of oldstyle numerals.

Given that all the other founts have oldstyle numerals, this seems a bit
odd.  Can anyone explain why this is?

Ah.  I see.  Yet more confusion...

I see - thanks.
