Re: unsigned type

Yea, Right! Like, how many people need a trinary system. There are a few, a 
very few! 

And as for Natural, well, that is the definition of a String's index and in most 
cases you use Naturals in "for loop' statements.

And if you use the standard types instead of creating your own you 
would save problem when another modifies the program! Alway use standard 
if possible, That way every program rather Ada or C or etc known the type 
and the range. 

Never create your own types unless lives are an issue. And most who use 
GPL GNAT are not writting program where lives matter.
