Dear George

Many thanks for your detailed answer. I'll most certainly make use of
your advice. However, if you look again, my question was not

- How can I verify whether a character is upper case

Nor was it

- Where, in the library hierarchies of Ada, can I find the character
handling routines

It was intended as "How do you translate this example to Ada? How would
you, as a presumably experienced Ada coder, do it? What hoops would we
jump through?

In other words, I wanted to see some Ada idioms in action to create a
transparent coding of this.

If you believe this simple exercise is not a productive use of your
time, though, I can understand.

Thanks again.
