Hi All,

I am new to Ada and found the following declaration in my text book:

type ASTERIX is range -5_000..+10_000;
subtype IDEFIX is range 1..20_000;

How can it be that the subtype IDEFIX can exceed the boundaries (20_000 
compared to 10_000) of the superordinated type ASTERIX? If it is a 
subtype its boundaries should be within the boundaries of the type it is 
derived from. Did I get something wrong?

Regards

Nobody
