Don't bother. The only reason you need inheritance is for dynamic
binding, which you don't have anyway in Ada83.
What is your interest in Ada83? Why can't you use Ada95?

Perhaps he means "generic actual subprogram"?
If all you want to do is reuse a subprogram, then you don't need
inheritance. Simply provide the reuseable functionality in its own
subprogram, and then call the subprogram.
No inheritance is necessary. No generics either, for that matter.
