I notice that in the Quiz of section 3.1 (Identifiers), you have a question involving underlines. As Netscape (browser I am using) underlines links, it is impossible to distinguish underlined from non-underlined. I don't know if you were aware of this. Cheers, Stephen.

More specific comments: ... (various bugs) I have some background in OO (MODSIM II) so was able easily to transfer my ideas from there to your Ada examples and text in section 7. I am not sure how easily non-OO people would react to these, but I notice in the 'to-do' that you mention this. Again, I found it very useful and good luck with adding further tutorial sessions.

Message-Id: <9502201541.AA0114@ankrums.asd.bet.ibm.com> Date: Mon, 20 Feb 95 10:13:31 EST From: "T. Scott Ankrum" <scott_ankrum@VNET.IBM.COM> To: wheeler@ida.org Subject: Lovelace Tutorial I just finished going through your Lovelace Ada tutorial and am sending you comments. Ada is not needed for my job. I am taking a programming languages course at American Univ. and our project requires us to learn two new languages. I spread the tutorial over three days. Two weeks ago I knew nothing about Ada, but I have been reading a small text and lightly browsing the Ada 9X reference. Your tutorial is very easy, possibly too easy. I doubt that anyone could write even a simple program with only Lovelace as his/her background. I am writing a small program using the GNAT compiler from NYU and I am having a lot of trouble understanding supplied packages. Lovelace helped me understand what a package is and how to write my own small package. What I am missing is an understanding of supplied packages. As a new Ada programmer, I need to know what I/O packages every Ada compiler should provide and how do I find what a particular compiler is supplying. (For GNAT, I am told I should be browsing ????.ads files.) In particular, I had trouble locating floating point I/O. Noone should expect to learn very much of a language from an on-line tutorial, especially a free one. One should expect to be able to write some simple (but more complex than "Hello World") programs to get started. Please try take these comments in the best possible light. I was very pleased to find an Ada tutorial on the WWW and I got a lot out of it. I am just trying to gave back a little with some (hopefully) constructive comments. In summary, my two suggestions are: 1. Make the unit quizzes harder. 2. Add a unit that talks about using supplied packages. T.

By the way, I think that this is a very good way to learn to use Ada. O can not only go at my own pace, but can do it when I feel like it. I'm now on section 7 and the last many sections have been really good, clear explanations, good examples and the quiz to make sure you're understanding. Well done. Are you constantly updating it, adding new pages? Cheers, Lee.

First, many thanks for your tutorial! I'm new to Ada, and I've tried to learn the language the last couple of weeks. Your tutorial gave me a "kick" to learn more about the language. I've finished the seven chapters, and I'm hungry for more... :) Well, you mentioned at the end that someone wanted to translate the tutorial into French, I'm interested in translating it into Swedish. I see this as a very good chance for me to learn more about Ada. I've a book written by Jan Skansholm in swedish, I belive the book has an english counterpart too. The title is (freely translated from swedish) "Ada from the beginning - with the Ada 9X standard". I guess you have heard of it, or even read it... Well, I thought of using it when translating your tutorial into swedish. This gives me a reason to read the book too... Well, if you think the world is interested in my project, please email me about it, and I'll start as soon as possible. Yours, Andreas Almroth

Very good! :-) I knew most of the material up until the OO programming, but it was a nice review. I hope you don't mind...I told my Real-Time Systems' professor about your tutorial. He had to teach Ada at the beginning of the semester and felt as though it cut into the course. Perhaps he will have his next class go through your tutorial instead. :-) One small thing, though...since many schools might still be using an Ada83 compiler (we are, however I convinced my system administrator to install GNAT for my project) perhaps you could cover a little more on those features. At any rate, it is fine tutorial for beginners and a good review for an intermediate. Take Care! Chris O'Regan Computer Engineering, Concordia University, Montreal, Canada.

As I have just started on Ada there isn't really too much I can add, except that the tutorial was very useful. I will be passing the WWW Ada address on to my other Uni. friends as I'm sure that they WILL find it very useful too. Thank-you for the time and effort in writing this.

Since I already was familiar with Ada 83 it did not offer much new to me, except of course the last section about object orientation. Nonetheless I enjoyed answering the questions since I was always right :-) While doing this tutorial I always had the impression that you created it especially for C/C++ programmers unfamiliar with any typical features of languages from the Pascal family, what certainly does not apply to me.

His language of choice is Ada, and so I have been using that while studying programming with a Pascal book: . My husband is a good teacher, and the authors have done a nice job of explaining themselves, but I think your tutorial has helped me the most. I thoroughly enjoyed your writing style. I also found your explanations of Object Oriented programming easier to understand than the text I have been using. What I appreciated most was the small, uncomplicated sample programs you used. So many books use examples that are three pages long and try to incorporated three or four new ideas. Thank you for this tutorial, and I look forward to your next. Lisa Mae Bronkema

It has left a good impression on me, the same good impression I had when I sent the e-mail two (?) weeks ago... I have more detailed feedback for you but I think that you should be aware that it comes from the perspective of a novice programmer ... I don't know what kind of people you were aiming for in LOVELACE, but I think it does an outstanding job of nurturing the interest of someone who is truly interested in Ada 95. I noticed that you described it as a whirlwind tour. I think that is true, but it was a whirlwind tour with many opportunities for brief reflection and with directions for detailed inquiries. Specifically, I think that the quizzes with comments for both the right and the wrong answers really helps a novice, like me, to get some sense of progress. Of course, more can be learned by working through full blown exercises but I think it might break the momentum of someone who is curious about Ada 95 in a self-motivated way. I also thought it was a good idea to include pointers to other sources of information about Ada. Additionally, I did take a glance at your strawman list of things to-do and am particularly intrigued by your idea of "dynamically" building a program within the tutorial. I do intend to nominate it for an educational Best of the Web, just as soon as that is possible! I feel that I have gotten something out of LOVELACE and would like to contribute something in order to show my appreciation. I looked at the Team Ada FAQ sheet, but I'm afraid that I'm not really in a position to do much help. About all that I can do is provide feedback of a simple nature. And congratulations to you and your wife about your baby daughter. Take care. Ted Mansueto mansueto@iastate.edu

I thought it was very well done. I've had minimal exposure to Ada in the past, but expect to get more involved now with Ada95 out and the mandate being more rigorously enforced. The lessons are broken up and ordered very well. I could do a couple of lessons each morning before getting on to my other work. The sections of each lesson are small enough that even if I got interrupted in the middle of a lesson it was only a short distance back to recover at a logical break. I especially liked the end-of-section quizzes. They tended to ensure that I absorbed what I'd read and hadn't just scanned it without engaging my brain (something that's easy to do when reading long technical documents). Even the sections with simple questions kept me awake, so here's an area for improvement: Add a Quiz to the sections that don't have them, even if it's just a regurgitation of what was presented a couple of paragraphs above. The only chance for improvement was that there were a few typos, these seemed to be more prevalent in the last few lessons -- in particular there are some missing or extra articles or connecting words. I think "prefin" is used someplace that should be "predefin". None of the typos obscured the meaning of the text. The hypertext links are also a good inclusion, I only followed a few but may come back for some more in the future. I have recommended this tutorial to my colleagues. Thanks for offering this resource. -- Chip Patton crpatton@ingr.com From: crpatton@ingr.com (Chip Patton) To: wheeler@ida.org Subject: A few typos located Status: RO David, Here's some of those typo's, the number in ()'s is the paragraph number in the section, at least the way I counted.

IMHO it is a brilliant idea to include more general sections like those on programming safety and efficiency. The only problem I encountered was that GNAT (at least 2.06 for OS/2) doesn't always raise Constraint_Error exceptions when it should. This is of course not your fault, but I think it would be a good idea to warn GNAT users that they might experience some difference between theory and practice - as long as GNAT is a work in progress.
