As someone else already pointed out, you should take a look at the
Ada.Container suite.  It sounds like you need a set or maybe a map.

The latest API is described here:

<http://www.ada-auth.org/cgi-bin/cvsweb.cgi/AIs/AI-20302.TXT?rev=1.19>

You can find a reference implementation here:

<http://charles.tigris.org/source/browse/charles/src/ai302/>

gcc 4.0 includes the ada.container library, so you might have it on your
system already.

I recommend poking around the examples directory for some ideas:

<http://charles.tigris.org/source/browse/charles/src/ai302/examples/>

I also recommend reading the !examples section that follows the
normative section of the AI-302 draft.
