As others have said it, it is a long tradition on comp.lang.ada to help when technical informations or "proof" of actual research is given. The answer to most of us in cla is trivial so it is hard to tell that it was not by laziness that it was not understood :) I hope you'll have a good exam.

I doubt that the exercise would use the word "generic" in this case. Just: function Bar (...; Foo : access procedure) return ...; -- Ada 2005 type Foo_Ptr is access procedure; function Bar (...; Foo : Foo_Ptr) return ...; -- Ada 95 But OK, in order to add a bit more confusion (:-)), there also could be a generic function which formal generic parameter is an instance of a generic parameterless procedure. Here it goes: generic ... package I_Have_A_Foo is -- We need an envelope package procedure Foo; end I_Have_A_Foo; generic with package Here_Is_My_Foo is new I_Have_A_Foo (<>); function Bar (...) return ...; Moreover, there could be a generic function which formal generic parameter is inherited from a generic ancestor: generic with procedure Foo; package I_Take_Foo is ... end I_Take_Foo; generic function I_Take_Foo.Bar (...) return ...; Being a child of I_Take_Foo, Bar receives Foo from its parent.

The word "generic function" has a formal meaning as an Ada term. This meaning is quite different from "a function with a procedure parameter", which has formal Ada meaning as well! A generic function that receives a procedure will be something like type Procedure_Pointer is access procedure; generic ... function Some_Func(Proc: Procedure_Pointer) return Some_Type; I guess you just want the third line. ^ permalink raw reply [flat|nested] 45+ messages in thread

Hi, I realised that the answer proposed here, is working great, but it's not really matching for what I was looking for. Perhaps I am looking for something that I did not understand well. While I was a student I got really sick, so now I got a special chance to attend the exam (3 years later), therefor, I had to study the language by my self. I understood the generics, but I was looking to make a generic function that receives an unknown procedure as a parameter, and runs the procedure. It's not like the 'regular' samples of " with function ">"(... " I was wondering if there is a chance of creating a generic function that receives an annonymous procedure. After trying to explain the question to you, I think I misunderstood the question, but still it bothers me. In any case, if I will not pass this exam, I will start bothering you here for the next few months :) Thanks for your willing to help. Ronit ^ permalink raw reply [flat|nested] 45+ messages in thread

Try thinking of a "non-empty" procedure and how you would specify that as a generic formal procedure. Then consider how, in general, you declare (a) a procedure with parameters and (b) a procedure without parameters. Combine the two results. ^ permalink raw reply [flat|nested] 45+ messages in thread

Actually, installing a free GNAT Ada version and starting to program is the BEST way to learn. Teachers only have time to give you an brief understand of any language. In the US that less than 45 hours spanning 15 weeks. Outside programming is the only way to gain a deeper understanding. And asking question with an expectation of an answer is the second best way to gain a direction for that deeper understand. Plus, in my many years experience if a person just say read a section or chapter than they also do not understand the problem or the language. Even my professor would not do that, they would give an example (like I did) and then assign someone an extra assignment that would include the example as a small part of the whole project. The only thing was their projects, either homework or extra assignments were too simple for me, (bored me to death). I actually had to expand them to make the worth my time. My Ada professor use most of my work in Ada to teach his other classes at two universities and wrote a number of text books using my classwork that were used in both Europe and US universities. What I did for my first Ada assignment after modifying it, was rated at doctoral level programming. I even had to have permission from 3 universities and their computer systems to fully execute the assignment. >Thanks a lot for your help. >I hope that some day I will be able to join this group as an equal >member and not just a student.

Hi, Thanks for your kind response. I just came back from the exam. It was not very difficult but I can't say it was easy. I don't believe I passed, but it's ok. I don't mind attending the course again, Ada is a nice and very powerful language, and I wouldn't mind getting to know it better. I'm going to get some rest now.

The Lady was not speaking of the "GENERIC" keyword in Ada. Also another clue was this was her first test. Basically, testing her knowledge of Reserved words, program structures, basic data types (defined in the "Standard package"), etc. And how to call a procedure and function, which as the base of her question. Testing for user-defined packages and possible the "Generic" type packages may be in second test.

But is it the best way to remove misunderstandings by again employing a misleading meaning of "generic" as in "generic statement" for "access to procedure" a.k.a. procedure pointer? (I'm saying this because communicating anything becomes O(terrible(n)), time consuming, entails anger and cost because misunderstandings can lead to work in the wrong direction etc. Words are then overloaded in a piece of information that should be specific, i.e., not overloaded. I'm not denying the usefulness of understanding what the intended meaning was, only that it should not be adopted.) >> >>> ------------------------------------------------------------------------------ >>> -- The Probability the answer that she ask for: -- >>> -- -- >>> -- type proc_access is access procedure ; -- is the generic statement -- >>> -- -- that she needed. -- >> I'm not sure I understand "generic statement" here. >> Proc_Access looks like an access to subprogram type. >> What is a generic statement? > ^ permalink raw reply [flat|nested] 45+ messages in thread

And since the original poster in this case, used the word 'Generic' that means that if I change the word it might confuse her. Just because others may listen in does not change the fact that I was talking to the original or previous poster. You use the language and semantics that the original or previous poster should know. That way they understand which is the reason the answer was given. Others may listen in may or may not like the answer given or even understand the answer, but that's their problem. Because the answer was not given for them, its for the original or previous poster. Also that English for you! We use the same word to mean many things instead of creating a new words. Plus, like all of us we use the semantics and slang that we know and sometime it can be confusing to others, but to keep the peace we must all learn to get over that. And only reading the last sets of posts of a thread one is more likely to misunderstand any and all parts of the thread. To help keep from misunderstanding someone, you first need to find the original poster and read what they stated. I knew what she meant and wanted from her statement, but in reading other post I was not sure they did. I think most posters just Keyed on the word 'Generic' and did not understand her complete question, so they tried to send her to the LRM chapter 12, that deals with "Generic Units". And the misunderstanding is not the original poster fault. You will see this if you follow the complete thread. She even lets people know that it had nothing to do with Ada's "Generic Units". Language misunderstanding can and will happen from time to time we just have to deal with it. That's the way the world works and its not going to change anytime soon.

Right, this is why I suggested that the confusion might best be removed by mentioning the misunderstanding in your program or near it. Like, "you called it generic, maybe because ..., but in Ada, generic means something different. So it is better to not call it generic and instead use ..." (You would have used that other, correct, word in your comment next to the access to subprogram type.) This would have cleared up the situation for her and for everyone else: (a) She would have known that generic means something different in Ada. Now she would have to figure that out herself (if necessary), in part because your comment confirms her misleading use of the word. This might leave one task open that could easily have been closed. (b) Everyone else would have said, Ah, I see. And presented more helpful pointers. > Plus, like all of us we use the > semantics and slang that we know and sometime it can be confusing > to others, but to keep the peace we must all learn to get over that.

(I suspect a few cultural misunderstandings in this--please consider I'm German and as such insufficiently restrained in NG discussions-- there is no excuse.) I should have expressed myself more clearly. I'm not asking anyone to ask questions so that I can understand them. Good heavens! I did suggest, even though you didn't ask me to do so, that *answering* the question can include an option to just provide that additional bit of information to the OP that will help avoid future misunderstandings on either side. There is of course absolutely nothing wrong with asking a question using whatever words one has available! However, I do think that *without* additional explanation, it is really doing a disservice when an answer calls an access type declaration a "generic statement" even when this is only done to refer indirectly to the OP's question. I shouldn't have told you what to do, though. Sorry if that comment hurts you. > Even if the world spoke a Single World Language there will still be > confusion, JUST DEAL WITH IT! Yes, certainly. However, IMHO, dealing with confusion in a NG does not always entail the silence and confirmative attitude you have to adopt when a superior asks you a question using technically unusual words. Again, nothing wrong with the question! And it is my task trying to understand the question. In a NG, there is a chance to provide information about words used in the question in addition to confirming the question, even when it contains a few bits that sound like a correction. I'll try to be more considerate in the future. ^ permalink raw reply [flat|nested] 45+ messages in thread

I tried to do the challenge, but really I didn't find the answer in the short time I had. I have to go to the exam now. If you don't mind, answering me just to help me understand, I will look at it after the exam, and maybe then I will understand. Now it's too late for me. BTW, I studied according to 2 books. 1 of them is not in English, it's of my university, and the other one is: Object-oriented software in ada95 2nd edition by Michael A. Smith. I read them both and did excersizes. Perhaps its because the stress, I can't figure it out now. I hope you wish me luck. I'll login in a few hours to see what I was missing..
