I agree it is inconsistent, but unless BASIC magically gains a
(backwards compatible) means of typing signed integers different from
unsigned, I am afraid we are stuck with it. 

The only way I can think of is to add a new Function keyword which
after and add or subtract returned the 4 possible flags for
Signed/Unsigned Underflow/Overflow. But I am not sure if it would be
any real use.
