asm
Author
Can anyone point me to a good assembly tutorial (x86)? I want to learn it just for the hell of it. asm always kinda fascinated me.
btw...and this is off my own topic, but is there any way to make a clear screen function in C++ without a system call, conio, windows, or printing a bunch of newlines?

No idea about the asm tutorials, sorry. But no, there's no portable way to clear the screen. The reason being that stdout doesn't have to be a screen. You could be outputting to a printer or some other device, and clearing the screen wouldn't make sense. Your best bet would be either using system("cls"); or a Win32 command (If you're using Windows).
Maybe you want to read from this page:

i hope this helps...
[source = "c++"]void clrscr(){ HANDLE hStdOut; COORD coord; ULONG area; hStdOut = GetStdHandle(STD_OUTPUT_HANDLE); coord = GetLargestConsoleWindowSize(hStdOut); area = coord.X * coord.Y; coord.X = 0; coord.Y = 0; FillConsoleOutputCharacter(hStdOut,' ',area,coord,&area);}

Thanks all, the links were helpful.
I didn't think there was a simple way to do it without windows or a system call, etc., although I thought maybe there would be some way to do it with \b and spaces, although the only problem there is knowing how many characters have been printed.

If you're in DOS, there should be a BIOS interrupt to clear the screen. Try poking through this and see what you can find.
here's a book that was released on the internet for assembly
