See the chapter about Access Types. There is an entry for dereferencing in the Ada95 book, pointing to two pages. Dereferincing those pointers (!) I find that what both pages say about dereferencing is that it's automatic, unlike Pascal. I read the Access Types chapter a few times, but didn't find the idiom I needed or anything that would help me to find the idiom. Now I know what the answer is, I can see it in Barnes, so I can't say he didn't cover it, but the way he did it wasn't clear to this particular newbie!
