"Dynamic" object

[randhol@pvv.org (Preben Randhol)]

I'm wondering how to do the following in Ada 95.

I want to have a small program as a frontend to a database. Thus the
program needs to read the definition of the db and then generate the
proper GUI for this. This I think I know how to to, but the problem is
how do I define a type that contains the different fields so that I can
put it in a linked list?

Example:

Field 1: First_Name (string of size 30)
Field 2: Sirname    (string of size 40)
Field 3: Age        (integer of size 3)
...
Field n: Address    (string of size 80)

Any hints much appreciated.
