Re: calling one top-level procedure from another

I am sure you will get a million responses on this one...

You need a "with" clause:

with proc1;
procedure proc2 is ...

Top-level compilation units (aka library units) are
only visible in other compilation units if they are
mentioned in a "with" clause.  As Steven Jobs would put it,
the Ada "with" clause is "insanely great."  Without it,
any module could call any other module with no indication.
The "with" clause very neatly identifies all of the external
references required by a library unit.
