Yes, this is the way to go, that's why the features were put into the
language.  The problem with doing a good generic package in Ada is
that it takes time, and on a "quickie" program you don't have the time
available.

I've got some pretty generic code around here somewhere for doing 64
bit ints in C, which you could probably convert to Ada and overload as
operators.  That assumes, of course, that you know C.

(My only hands-on experience with Ada overloading was a package I
wrote to handle 48-bit binary numbers as characters for a program that
decoded messages on a DoD embedded network.  The package wasn't in the
version that got qualified and shown to the world, unfortunately.)
