Ken Garlington asks:

"   type D is delta 0.1 range ...

This generates a set of model numbers M. In this particular user's mind,
however, he is thinking in terms of the set S = { ... 2.0, 2.1, 2.2 ... }
(is there a name in Ada for this set?)."

No, there is no name for this set as the declaration stands. However, if
the user is thinking in terms of this set, then the following declaration
should be added (Ada 83 or Ada 95)

     for D'Small use 0.1;

then there *is* a name for that set, its called the set of model
numbers and things will work exactly as expected.

If your compiler rejects this declaration, it is being naughty and you
should complain to the vendor, there is no god excuse for not supporting
decimal small values.
