Help out a Newbie

[Akinsanya, Babatunde O.]

Hi all,
	Just a quick question and a sample code. I am new to Ada and I
just want to know where I can get a windows (preferably win'95) compiler
for Ada. 
	Second, I tried compiling this sample code and I got the following
errors. I am working on a unix system using DEC's ada compiler.

with Ada.Text_IO;
procedure Hello is
begin
	Ada.Text_IO.Put ("Hello world!");
	Ada.Text_IO.New_Line;
end Hello;

This is the error message.
with Ada.Text_IO;
--------^
ada: Error: t.ada, line 1: Found "." when expecting one of { "," ";" }

end Hello;
ada: Error: Terminating compilation due to syntax errors in file t.ada
ada: Error: Ada compilation completed with 2 diagnostics

Thanks,
Tundey

If this is not an Ada95 compiler, you might try what the error message
suggests. Remove "Ada." from all references.

Good choice!

For learning Ada95 there are currently two compilers on the net: GNAT
3.10p1 and ObjectAda 7.1.

Both are already very good compilers. ObjectAda is more Windows Centric
(it's IDE looks a lot like the MS developer studio, supports a lot of
Win/NT stuff) but the free version has a number of build in limitations.
The GNAT compiler is more UNIX-like, although it also includes an basic
IDE.

As you are working on DEC hardware, GNAT might be the best choice, as it
will also become (or already is) available there.

There are links to download both compilers (and the homepages of their
makers) on my homepage: http://www.stad.dsl/~jvandyk.

The current DEC compiler conforms to the Ada83 standard, in this version
of Ada, the Text_IO package was a top level package, not a child of Ada.
If you replace Ada.Text_IO by simply Text_IO your program should work.

(P.S. Ada95 defines Text_IO as an alias for Ada.Text_IO so this will work
 either way :-).


Good luck!
Jerry.
