Working with GNAT Ada

Working with GNAT Ada

[James H. Robinson, III]

I typed the following code from my textbook into GNAT Ada 95:

-- Precompiled instantiations of Integer_IO and
-- Float_IO for the predefined Integer and Float types

WITH Text_IO;
PACKAGE My-Int-_IO IS
	 NEW Text_IO.Integer_IO (Num => Integer);

WITH Text_IO;
PACKAGE My_Flt_IO IS
	NEW Text_IO.Float_IO (Num =>);


When I tried to compile this code, I received many error messages such as
my needing and END statement and my needing declarations.  I don't have a
clue what's going wrong.  Is this due to a difference between Ada83 and
Ada95?  The problem is, I can't do any of the other examples in Chapter 2
until I get this instantiation working.

Hyphens are not legal characters in identifiers in Ada.  You been
hackin' Lisp recently? :-)

Works fine if you fix the syntax errors.
