Hey guys, I have a problem in i8086 Assembly.

I try to make the following test :

If the users press "enter" (carriage return), the program jump to the end

In ASCII code, I can try it with 10 (new line) or 13 (creturn). Here's my code problem :

MOV AH, 01H
INT 21H

CMP AH, 10 ;10 = carriage return
JE end

With this code, when I run my program, I'm not able to interupt the program when I do a carriage return, so I'm block in an infinite loop ...

Could you help me plox ?


/e Even if I swap AH for AL, nothing it happen

not sure about i8086 but in there should be a specific interrupt you have to call to call to be able to read anything in on stdin. you cant just mov ah around hoping that you capture something.

nvm

Ok so I just find my error ... They were an error on my JMP label .... Label was "End :", and it should be "End:" without the space ^^.
I'm an accustomed of bash but I didn't think there were also this kind of problem in assembly



MOV AH, 01H
INT 21H

it's the interupt I have to call in 8086 to read an entry in my stdin

yea but say for instance in x86 32bit asm on linux you also have to supply a buffer to store the stdin data, the length of the buffer and other details before the interrupt call.




not sure how 8086 works though never used it

oh ok, u were talking about the stack size ?

In 8086 it's this kind of skeleton :
