Two years ago you did the same thing. How about you show us that you're learning, show us that you're thinking clearly and carefully, and ask a coherent question.

It is a standing policy of this board and its members to not complete the homework of students. I'm sorry, you'll need to derive the solution yourself.

If you genuinely want to program in assembly language, you're going to have to work very hard on improving your care and your attention to detail. You paste blocks of code but otherwise you take no care at all.

How about you put some effort in to think clearly, express your thoughts clearly, explain what you're trying to do and in what respect you're getting stuck?

This is usually a friendly and helpful forum, but you're not acting like someone who's interested in understanding or improving - you're acting like someone who expects a free gift.

Edit: refer to previous conversation 2 years ago, rewording.

Even after doing the above, it's not at all clear as to what is going on—a comment in this source code would die of sheer loneliness. I really don't have a clue as to what he is trying to achieve.

In any case, Ed's comments stand. As the old saying goes, "The Lord helps those who help themselves." You (Amenofhis) wrote it, you figure it out.

actually is not my homework.. i just had corius of programing.. a friend is teaching me... how to work in but still he dont know much... thats why im asking here.

i still see all the 0... here what i want to help me with it
5x5=25 is the multiplication i leave for you guys to help me with it
the anwser appears but appear 0000000025000
i want that only appear 0 i want to eliminated the bits that are not using
so i want to be 25 instead of 0000002500 and if u mulptiply for 0 the result is 0

what i want to do (simpify) all the result to its digit and all the ress gone.. how i do this

oh btw im not student im just curius to learn this languague sorry if u guys think of me as a student

This same time of year, two years ago, you had a similar problem:

Amenofhis wrote:

thats all i got for know that was the teacher told me, he teach about LSR and ASL but i didnt understand a thing

He said

Make a program that move a bit right to left and left to right in a Velocity of 10 seg and can be desplayed on the Screen that all i got.

im thinking and still not getting it.. Thats why i require help. cant do it my own im sure of that im not in the 6502 much.

Maybe you are re-taking the same course? You are still having trouble with the homework, and when you ask for help - actually you demand help - you really want someone to solve the problem for you. That kind of help isn't real help: if you pass a course by having other people write your programs, your qualification is not valid.

I think this program isn't yours, or your friends. It's an exercise, with an intentional missing feature that you have been asked to implement.

If you really want to learn to program in assembly, you need to work harder. You need to become a careful person who cares about details and tries to understand precisely what the problem is - only then can you create a solution. You may need trial and error, but if you do, you should take careful notes of what you've tried, what happened, and what the explanations might be.

That and get in the habit of commenting your source code! Most of us are quite busy and can't expend a lot of time trying to deduce what was going on in your head while you were pounding on your keyboard. If you want help, please comment your code, clearly state your problem and ask for help NICELY.

wait im 25 years old im already graduted and i call teacher everyone that is teaching me

and yes i ask around and yes i had a teacher from collage and yes i really asked for help but that was 2 years ago...
either way i do not understand fully enough about this lag programing but im traying to if i cant do it i ask for help if u can explain me how instead of lecture me then i be glad if u been doing some research of me im glad too

Hi
I really don't want to be discouraging or unhelpful. I hope you've understood and accepted the idea that to program in assembly you need to be careful and methodical. Similarly, to get help in a forum - to earn the right to other people's time - you need to ask a meaningful question with some indication of what you know and what puzzles you, what you're trying to do and what you're seeing. Pasting a huge chunk of uncommented assembly isn't polite.

Cheers
Ed
