It's always odd when you have a situation where Ada provides
an approach X to solving problem Y that works in a perfectly
straightforward manner, and then asks

How can I do Y without using X, because I don't want to use X.

That's the situation you are in here. Catching End_Error is a
clean solution to your problem and is the recommended approach.
It is also often the more efficient approach compared to an
explicit end of file test in the loop.
