Assembly Language: Transposing This Souce Code

Good Day All,

I have a problem. I'm new to assembly programming and i have no idea how i'm gonna do this task. I need to write a program in assembly language and i'm not familiar with the syntax but i've written the pseudocode for it. I was wondering if anyone could help me transpose this.

set x=y=0
loop 3 times
z = get valid digit from the keyboard
draw suqare of size z at (x,y)
y = y+z
end loop

I need to do this in intel x8086. i'm not too sure how to pass values in a parameter list in assembly language. do i use a stack for that?

any amount of help will be greatly appreciated.

Cheers.

Yes, it is recommended to use a stack when making function calls in ASM:
Example:

MOV ax, 50
MOV bx, 20
MOV cx, 20
CALL ADDER
...
ADDER:
; Only using dx to show that you can preserve registers this way.
PUSH dx
MOV dx, cx
ADD dx, bx
ADD dx, ax
MOV ax, dx
POP dx
RET
