Marc says

<<type foo is array (1..512) of character

foo'size reports it to be 4096 bytes in length.

I tried:

        pragma pack (foo)

I tried:

        for foo'size use 512;

none of them work! help! I am going out of my mind trying to figure this
out.


Thanks in advance,

A good idea in such a case is to check your assumptions. You are assuming
that Size yields the size in storage units, but let's read the RM:

40  X'Size
                Denotes the size in bits of the representation of the object.
                The value of this attribute is of the type universal_integer.


Ah ha! bits!!!
