Yes, of course! We were talking about how Ada _ought_ to deal with uninitialized variables. Therefore, we must be talking about hypothetical languages that are different from Ada. >...so that's where the misunderstanding was. My position had a > premise that we're dealing with Ada integers as they are (that is, > non-abstract, and without a null value). Yes, access types have null, and integers do not (in Ada). But that's not a good argument that access types _should_ have null, or that integers should _not_ have null. "It's best if Ada does X, because Ada does X" -- that's circular reasoning. ;-) - Bob
