Hi Everyone

I love Ada and I am so grateful for the help I have received on this list. =
This post is slightly negative and I really hope I will not offend those th=
at have been so good to me....

With Ada we can define exceptions and they have an explicit place in the bl=
ock structure. It appears that this form is called unchecked exceptions.

There is also checked exceptions, like in C:

if (f =3D fopen("someFle")) { do something ... }

Assuming that a valid test can be created, what is wrong with checked excep=
tions ?=20

I love Ada but I have found that I don't need a large part of it as a singl=
e developer writing single threaded code.
  =20
Tying my code to a built in exception model means I have to choose other la=
nguages that have built in exceptions models like C++(yuck) if I want to po=
rt and that doesn't mean that there models work the same way. Checked excep=
tions look easy to port to virtually any language not just C.

Please help me understand the benefits of Ada's model.

Thanks for reading-Patrick
