)Why is DOS confused? I mean, Prefs seems designed to allow extensibility.

The dos does some validation based on size, wrongly, which effects
moving preferences file from new disks to old, and so on.

I hope you didn't assume it was usable by a program other than morerows
or the equivalent.

)Too late... my 'prefs' program (posted to comp.sources.amiga) lets anyone look.

Hey, that's great.  Your program or users' behavior might interfere
with later system software.  I expect the users will be able to tell.

Too bad.  I hope you don't count too heavily on its values, which are
not documented.

Well, I was kind of counting on that.

)I *am* using the new fields. When I wrote the program I just copied the fields

You'll like V1.4 Intuition: nothing you aren't allowed to play with in Intuition
will be present in the include files.  I'm assigning Reserved[4] to a
function key.
