Thank you.

Well I have instantiated generics for text io, enumeration io etc but this
iteration generic threw me for a loop (pun intended!) Maybe it was the
double indirection. First you have to define a procedure and then
instantiate the generic with your procedure. I guess I have only understood
how a type is given to instantiate a generic, not a procedure.

The package spec does explain how to use the API as far as I can see, not
having tried it yet. The issue for me is not knowing Ada enough.
