Subject: Re: 'SIZE attribute of a type

Well, now for the twist. If I have understood this thread, the following
statement should minimize the storage for variables of type b:
for b'Size use b'Size;
So I used a Verdix compiler (old) to see if it would even compile the
code--it does! But for a Boolean type it still uses 8:
Domain/Ada Version 3.0.2 - March 23, 1990
Type B has size 8
Variables of type B have size 8
How many compilers can compile this and then how many actually
use one bit for this type? Very interesting...but cryptic.

with Text_IO;
procedure Test_B is
type B is new Boolean;
for B'Size use B'Size;
B_variable : B;
begin
Text_IO.Put_Line ("Type B has size " &
Integer'Image (B'Size));
Text_IO.Put_Line ("Variables of type B have size" &
Integer'Image (B_variable'Size));
end Test_B;
