    I don't know what is a "package global", but when I develop a
program bigger than the gadget I used as example, the 1st thing I do is
to write at least one package, or typically a tree of packages for the
application. I use to write applications bottom-up.

    Ada comes with two trees of packages, the root of which are Ada and
System. You need to add your own to put your own type declarations and
subprograms. You can also use ready-made third-party packages; for
example, there are GtkAda and Gnat Spitbol. The last implements the
SNOBOL4 string manipulation; I remember it was real fun.
