Now you have got me! (-:
Okay, so GPC will have `FooInt' for signed, `FooCard' for unsigned integer
types, and `FooWord' for types where we don't care about signedness (and
which are in fact unsigned).
These are many Integer types for GPC - much more than in BP. So let's hope
that this will lead to clear programming, not to confusion ...
