Wait, let me see if I understand correct.
A b_call calls a subprogram which is stored in the Include file. So, for example,you don't have to set each pixel to make an "A" or "B". You say: Output this letter here! While assembling later, SPASM searches in the include file for this letter and exchanges the "Output this letter here" with "Set these pixels". Right?

Not quite. A bcall is like a subroutine, except it's provided by the OS.

The bcalls are a bit more complicated than that. What you will find in ti83plus.inc is an address for the bcalls. Someone else can probably explain this much better, but i believe essentially there's a big table which holds the address + flash page of the bcalls. The bcalls are stored in the OS, the include file just provides you with an easy way to access them. Rather than remember the address in the table (for example, $450A for _PutS) you can just type the name. There isn't any code in the include file so it won't increase the size of your file any, there are only equates.

I can confirm that bcalls use a vector table.

Let me see...
So are there good tutorials except of 28 days and Hotdog's?
And where do I find Hotdog's tutorial?

I'm sorry for my whole questions, ASM is just a trouble :/

The only tutorial I ever used besides ASM in 28 days and the other existing ones when I tried learning ASM was ASMGuru, but the learning order is weird and it's only for the TI-83, not the 83+, so it might confuse you even more when you switch back to the 83+.

I highly recommend CoBB's z80 guide:
http://sgate.emt.bme.hu/patai/publications/z80guide/

I started with AsmGuru back in the day and thought it was great, but really all it teaches you is how to use bcalls and work with system flags. Not too useful if you want to get started on games as you won't really understand the logic behind things. CoBB's tutorial provides a more theoretical approach i think as does 28 Days and will get you much closer to being able to dive into your own games.

I never spent too much time looking through Hot_dog's tutorial, it came a bit after my tutorial time, but it's in the Omnimaga archives:
http://www.omnimaga.org/files/Our-TI-PC-Products-Music-and-Calculator-Videos/Our-TI-Documentations/

EDIT: You might want to check out the "readme" to CoBB's tutorial, it's got a nice explanation of the dangers of just using other people's code (or BCALLs) without really understanding/taking the time to understand what they do:

Hot_Dog's tutorial is more for people who are visual and cannot learn without concrete examples that are interesting to them or real life analogies. IIRC he said it was meant to be used alongside ASM in 28 days.

Thank you (both).
I think in about a year the NikProgrammer TM will open it's assembly factory and start produce software :blah: :D :-\

The best thing you can do in my opinion is start with a couple small projects and gradually go from there. Really once you get the concept of spriting and tilemapping down there's a whole lot you can do. And of course ask lots of questions. Smaller projects are much more encouraging as you will actually finish them, most (but definitely not all) larger projects remain unfinished or, as was the case with The Verdante Forest, end up burning you out and making you leave the community once the project is actually finished ;) Off topic a bit, i really wish Maarten/Kozak had released the source, i would've liked to try fixing the huge lag when there are lots of animations on screen.
