New to ada.

[Seth Hettich]

I just started using ada (verdix) on a sequent. I'm looking for a way
to get large integers. But it only appears to support integers up to
2^32 -1. Is there a way to get integers that can range from 0 .. 2^72

Re: New to ada.

[Robert Dewar]

All GNAT compilers support integers of 64 bits, and to a somewhat limited
extent (basically arithmetic only) up to 128 bits using the so far
undocumented :-( entity Standard'Huge_Integer. Of course use of the
latter is not likely to be portable to other compilers, it is really
intended for internal library use.

  Hi all.I'm new to ADA and want to explore the language.I bought the
Walnut Creek CD ( July 94 ) and would like to get recommendations on
which compiler/editor to use which would be good for a beginner.I have
some Pascal,C++, and basic programming background.
Thanks in Advance.

[Dennis East]

Need some assistance getting started in ADA
In the following procedure I am getting 
"invalid parameter list in call" 
just trying to get a 3 character month string, and have made several
changes but seem to get one error followed by another.

-- Procedure to get the date in the format dd,mmm,yyyy

with gnat.io; use gnat.io;
procedure get_date is

type month_name;
type month_name is (Jan, Feb, Mar, Apr, May, Jun, Jly
   , Aug, Sep, Oct, Nov, Dec);
mon: month_name;

type date_record;
type date_ptr is access all date_record;
type date_record is
   record
      day: integer range 1..31;
      month: month_name;
      year: integer;
   end record;

D,date_rec: date_ptr;   

begin
   put("Please enter the desired date ");
   date_rec := new date_record;
   D := date_rec;
   get(D.all.day);
   put("Enter Month ");
   get(D.all.month);	-- Error occurs here
   D.all.month:=mon;
   put("Enter Year ");
   get(D.all.year);
   new_line;
   put("Date entered is ");
   put(D.all.day);
   put("-");
   put("D.all.month");
   put("-");
   put(D.all.year);
   new_line;
end get_date;

It is possible I'm overlooking the obvious, so another solution could be
used also.  In final package I will need to input name strings into a
linked list record, so I need something similar that works.

Thanks for any assistance.. Dennis

I've never used Ada but I like to check new things out. C++ and C appeal to
me Java not so much. Is Ada a compiled programming language? Is this Ada
that help Charles Babbage with his counting machine?

Yes. If you want to try it look for GNAT (GNU/Ada compiler) or Aonix ObjectAda
which make available a free (yet limited) version of their compiler.

> Is this Ada that help Charles Babbage with his counting machine?

No. Ada first normalization was on 1983 named Ada83. The second norm was
from 1995 which is called Ada95 or just Ada at this point.

To learn more about Ada:

Look for the AdaFAQ, but there is also plenty of resources there.

Well I misunderstood the question :). No Ada was not used by Charles Babbage
but yes Ada Byron, Lady Lovelace (1815-1852) did work with him.

Sorry for the confusion.

The first Ada standard was MIL-STD 1815, 1980 Dec, "Ada 80". This was
followed by ANSI/MIL-STD 1815A, 1983 Feb, "Ada 83", which was adopted
unchanged as an ISO standard in 1987. Then came ISO/IEC 8652:1995, 1995
Jan, "Ada 95" or just "Ada". Currently work is under way to create Ada
0X.

The computer language was not around back then :-), but yes after it
was developed the language was named in honor of Babbage's coworker,
Lady Ada Lovelace.  Apparently the originators thought it was a better
name than STD-454325499638 or "Green".  It isn't easy being "Green".

New to ADA

I'd like to investigate ada a little I'm used to C and C++. Is ada as
powerful as C++. Does it have inheritance, OOP, classes or something
similar. I know one command with ada 'with'. Is there a compiler for windows

I don't use interpreters.

Yes.

Oh, you probably wanted more details.

Ada is as powerful as C++, even more powerful when you consider that
Ada has built in syntax for concurrency, while C++ does not.

Ada does have inheritance, OOP, and something similar to classes.

I use the GNAT compiler on my Win 98 laptop. It works very well.
Gnat is a compiler in the GNU compiler collection.

I will be immodest enough to suggest an introduction to Ada that I
recently wrote. You can read it at
http://www.crystalcode.com/codemage/MainMenu/Coding/Ada/IntroducingAda.php

This introduction is NOT a full tutorial on Ada. It is merely an introduction
to some of the major Ada features. Other tutorials can be found at

Well, "Whatever C++ may do, Ada may do it as well". You will find all
modern features in Ada. But Ada has something, that C++ does not have
- built-in concurrency. Its tasking model very strong and allows
to write you sophisticated and powerful concurrent programs
(my favourite Ada feature).

>Does it have inheritance, OOP, classes or something
>similar. 

Yes. Adding more - it has also something like templates - generics.

>I know one command with ada 'with'. 

So, come on, explore it! I'm sure you will like it.

GNAT:

You may also try ObjectAda from Aonix. It has environment similar to
this from Visual Studio. However, the available special edition allows
to compile no more than 2000 lines of code, but it should be enough,
if you want use it just for learning.

New to Ada

[mig20022000]

Hello. I am very new to Ada. I come from a C/C++ background and the the free sources that I have found on-line just don't make sense to me.

The way I usually learn new languages is by starting from basic algorithms. usually bubble sort and so on to merge sort using multi-threads. 

I was wondering if anyone could help me figure out how to write a bubble sort with user input. 

I will be more than happy to start a website with detailed tutorial of how to do any of the practices that I do so other people can pick up this amazing language.

Thank you in advance.

Check John English's Ada Craft book, it's free online. 

Don't try to learn Ada like people do with other languages by not using a
book and trying to plug stuff in "that looks like it should work" because
it won't. I think this is one of the problems people have with Ada.

Don't forget to post a link to your blog.

If you find missing examples on Rosetta, or radically simpler ways of

I did ask him if he was going to, said he wasn't.

It's not cheap either, might be better to try to get teh publisher with Norman's help to release the sources, it's not like they're printing anymore and won't be making any money on it.
