does anyone know a good place with a guide like Crimsons basic but for ASM or C?

as my AFX2.0 will be here in under a week and i want to program it in C or ASM, C is preferable

[betoe]

Well i think that for learn assembler programmation, first you need to know the hardware of the calculator, maybe you can download the Mohamed's english traduction of an AFX document (made by Olivier COUPELON), see the topic in the main forum, also there is an introduction of how to use the C compiler in that document.

[CrimsonCasio]

thats what I'm using

What's the name of the topic ?

[Roeoender]

I did it the hard way - I wrote all my C/ASM code by myself, but this is rather long and discouraging task.
So my advice is - look at all casio sites in search for games and programs that come with the source code (even I released some of it) and learn from it (eventhough some of them may be in terrible style).
As I remember: Mysterious island, older Touche, Highway, Cube3D, Scorch (not sure) and probably some more from the french.
If you don't know anything about C or ASM then first of all start programming in it on PC, when you will know how pointers, etc. work then switch to the calc.
BTW don't bother with C++ for the calc.

As usual I am a busy man so do not PM me, ask here at the forum.

What's the program ?

[Andy.Davies]

for C on the PC u will need visual C or Borland C, for a C compiler i have chosen Pacific C and Turbo C

[C@siomax]

I made a huge tutorial concerning C/Asm on graph100 but you need some basic knoweldge if you want to understand something !!
Anyway, yo can find it right out there

of course it is fully in english

[Andy.Davies]

thanks c@siomax, now i have two guides, which i can cross refernece between

But I can't download it !

[Andy.Davies]

hmmm, i managed to download it perfectly, and straight awy

Yes, My ISP had a problem that it solve quite !
Thanks.

thanks c@siomax, now i have two guides, which i can cross refernece between 

But at first where I input ASM/C Code ?

[Roeoender]

Hey P.J. please reduce your question-per-week ratio. We aren't here to answer your short,general questions. You have to investigate it by yourself (look at the net/ read books) and then if you really have a question (specific one!) then ask it.
You know programming is a creative art, you cannot only ask how to do this and that, you have to think, and try to solve problems by yourself.

You can treat this message as a warning.

What about Visual C++ ?

[Roeoender]

And how about reading carefully other posts?

Only C !

In http://www.microsoft...?displaylang=en I only find "Visual C# .net" not Visual C

[Andy.Davies]

sorry, but i dont know where to get it. just use note pad and turbo C or pacific C, to find those, just goto google, and type in their names.

[C@siomax]

I'm sorry for replying so late, but C++ code works perfectly on afx2 .... look at mx3d or shadow world ... fully made in c++ !!
Note that you can compile using another gui !! like context or vc++ 6, but you need turbo c to compile, and configure correctly your gui to launch tcc.exe using the correct arguments to build an exe file compatible with the calc

[CrimsonCasio]

whoa, really? vc++? could you go into a little more detail, this is very interesting to me. (since I already know C++)

could you please send me the source code?

[Roeoender]

He simply uses VC++ 6.0 as a IDE (editing and launching the compilation) but actual compation is done by tcc.exe so it doesn't give you much (personally I use BC3.1's IDE) - it is more less like using emacs and it's external compilation feature.
BTW C@asiomax probably didn't read all those threads about C++ here, I said that you can use C++ but it is simply unpractical.

[CrimsonCasio]

can somebody tell me whats wrong with this function, Its strait from the code of scorch, but the TC gives me an error every time:

void clrScreen(unsigned int seg)
{asm push es;
asm push ds;
asm push si;
asm push di;

asm mov ax,seg; //error: Expression sentax
asm mov es,ax;
asm mov di,0;
asm mov al,0;
asm cld;
asm mov cx,1024;
asm rep stosb;

asm pop di;
asm pop si;
asm pop ds;
asm pop es;}

I'm just trying to compile it and see if it works.

-----EDIT-----
ok, i figgured out its giving me an error every time ax is used, why?

[Andy.Davies]

yeay, i know C++ already, could u send me some instructions on how to setup VC++ to use turbo C or Pacific C ?

[PJay]

But you said :

C@siomax, Thank You !

[huhn_m]

Yes you even can program in pascal if you want ... (someone said ...)

but isn't it speed we want? And isn't it compatibility you want? If you only use vc++ as compiler where is the sense? You
can even use an editor in this case. And @crimsons ... If you write your code this way why don'T you write directly
in assembler? Don't you know that c code is about 10 times as large as asm code (sometimes) and (nearly every time)
also 10 times slower? I don't understand how someone can write c code and says asm would be difficult. who does so
doesn'T program himself but only uses other libs since they MUST be written in asm in order to make them work with
the calc. And if you write those libs yourself you also can write your whole prog in asm and use asms advantages ...


(just my opinion)

[CrimsonCasio]

I dont write code in ASM, I'm just trying to compile the code for Scorch on my computer and it wont work, the way I learn is by making changes to existing programs to see what the effect is, but I cant compile a singe one. if I knew why then mabey I could start programming in C.

[huhn_m]

the line you marked that gives the error makes no sense.

You must define what segment (of what variable)

e.g.

MOV AX,seg dudum ;Moves segment of var dumdum to AX ...

[CrimsonCasio]

seg is a variable, is that wrong?

[huhn_m]

seg shouldn't be one since it is (often) an operator that, if given in front of a variable
refers to the segment the variable is stored in.

[CrimsonCasio]

I changed it to segm and now it works, I wonder why he did it like that? (in one place he does hav segm instead of seg )

[huhn_m]

maybe just a spelling mistake ....

[Roeoender]

SEG is an assembler keyword (a directive to be exact) it simply gets the segment value of a variable that SHOULD be after it - so now you see why it caused the error - you treated seg as a variable when compiler interpreted is as a keyword and expected something more.

As for huhn_m:
I don't believe you don't understand why people use ASM as a part of their programs.
Ok here is the story:
when you use a profiler on any program you will see that some parts of programs (like plotting a sprite, putting a pixel, clearing the screen) are, especially in games, called *very* often and thus the whole program's performance depends in about 70% on those tasks, so people try to code those strategic parts in the fastest language - machine language. Putting some parts of code as those "asm xxx" statements gives you *none* peantly comparing to externally compiled .asm file (acutally you can compile .c files via assembler).
Ofcourse it would be the best if everything was written in ASM (fastest and smallest code), but some other non performance-dependent tasks (like getting keyboard input from the user) can be written in easier to use and easier to read/maintain language (like C). I don't know how many programs you wrote, but please write 10 programs in ASM, don't look at them for a year and then return to them to modify some even simple part (I had to add changes to linl and txtview in this maner) - I am sure it will take you ages to understand what you have written year ago (unless for every line of code you write 2 of comments, but then why not write in C - less work).
My opinion and about 90% of the population of practical programmers (10% is even more lazy).

this isn't my code, its the code in scorch, I'm wondering how he got this to work in the first place...

[Roeoender]

Yes I know, he may have used some older compiler, anyway I haven't used anything older than BC3.1,
but even in this version compiling ASM parts can produce some strange errors, so in his compiler it could be this way that the seg-variable hid (overlapped) the seg-asm-directive so everything was clear. It is common that some less important/external things are don in compilers in a crappy way (they quickly addapt huge parts of external source code etc.).
Congratulations in deciding to learn C/ASM programming - it is really worth the effort.
Roeoender.

[CrimsonCasio]

I'm taking a college course on it just so I can make games in C for my calc

[huhn_m]

As for huhn_m:
I don't believe you don't understand why people use ASM as a part of their programs.

I didn't say this ... read my post!

I said: *You must write main parts in asm*
and I said that if they can do this it should be no problem for them to write the whole prog in asm ...

As for huhn_m:
I don't believe you don't understand why people use ASM as a part of their programs.

Well sure i'm not as experienced as you are but i wrote at least 8 progs (including 3 completely rewritteln <{GNULINUX}> version wherer only 2 were released) and I looked at some code of my first <{GNULINUX}> release (03/2003) to look how I did sth there. And I must say I
could read it very well ... I only commented about every 20th line and there params used for macros and procs but I used
variables names that make sense and since I know how most commands work it is no problem for me to see what I've done.
Sure it will be a problem for someone who doesn't know my style ... But I think someone who can'T reread his own code
without commenting every line ... well ....

[C@siomax]

loooool!!
Personnally I can avoid comments because of the structurated code I write now(not like bomberman), using structures and explicit names !! Non-programmers can understand my code very well !! But don't follow my example ... I add comments at the end coz I find it boring to explain ....
About asm stuf ... I fully agree with Roe !! Asm is indispensible to make a program running at a correct speed !! For example, I write many of my routines in C, but I take some time to translate them into asm """"little"""" tasks which you don't take care of can make you win sooooooooh much time

[Andy.Davies]

doest the AFX have a string compare (in ASM or C)? cos i think it would be quite useful, i cant wait until my AFX arrives

[Roeoender]

I've commented this part of your post:

If you write your code this way why don'T you write directly
in assembler? Don't you know that c code is about 10 times as large as asm code (sometimes) and (nearly every time)
also 10 times slower

Mine "I don't believe..." sentence was not precise (my fault) it should be:
>>I don't believe you don't understand why people use ASM as a part of their [C] programs,[and not write everything in ASM]. <<

You are still working on <{GNULINUX}> so you remember all the stuff, but ater <{GNULINUX}> write 6 more programs for the calc (and 5 more for PC) in a year and then return to your <{GNULINUX}>.
Ofcourse everyone has his times of fascination about ASM language, but someday he finds out that it is not needed (or even harmful) for some tasks.

Another quote from your post:

I don't understand how someone can write c code and says asm would be difficult. who does so
doesn'T program himself but only uses other libs since they MUST be written in asm in order to make them work with
the calc.

So 90% of all programmers programming for *NIX are not "real" programmers because they use system calls, libraries like curses, glibc, or maybe C++ are not "real" programmers because they use STL library, adn even C programmers use standard library so they are not real programmers. lol.
I think that modern programming (sadly or not) is all about using libraries.
Ofcourse CASIO AFX is so simple you can do everyting on your own, but I wouldn't force everyone to do so (but ok, I do this way) and reinvent a wheel. And using someone elses code (if legal) doesn't mean that you're not a programmer, only if you steal someone elses code you're a lamer.

Agreed with C@siomax - I also use C for "prototyping" I did like this with sprite plotting - which I rewrote in ASM later.
