We don't do your homework for you. Show some effort of your own toward solving the problem before simply demanding code.

.model small
.code
org 100h
start:
mov cx, 5
L1:
push cx
L2:
mov ah,2h
mov dl,2Ah
int 21h
loop L2
mov dl,0Ah
int 21h
mov dl,0Dh
int 21h
pop cx
loop L1
mov cx,5
L3:
push cx
L4:
mov ah,2h
mov dl,20h
int 21h
loop L4
mov dl,2Ah
int 21h
mov dl,0Ah
int 21h
mov dl,0Dh
int 21h
pop cx
loop L3
exit: int 20h
end start
I just can do this... (> <) to display
to display the triangle below, I still can not....

There's a flaw in your second loop. You're printing the right amount of spaces, but you're only printing one *, hence you don't end up with this:
> *
> **
> ***
> ****
> *****
To achieve the above, you need to introduce a counter much like you did in your first loop so that after you've printed the spaces, you print 1 * for the first line of the above pattern, 2 for the next and so on.
It's a bit difficult for me to put into words clearly, but I hope it's helped somewhat.

Hi,
Can you give a test to this code:
.286
.model small
.stack 1024h
.code
start:
mov cx, 5
first:
mov bl, 2ah
mov bh, 1
call drawall
loop first
mov dx, 5
second:
mov bl, 20h
mov bh, 0
mov cx, dx
call drawall
mov cx, 6
sub cx, dx
mov bl, 2ah
mov bh, 1
call drawall
dec dx
jnz second
mov ax, 4c00h
int 21h
drawall:
push ax
push bx
push cx
push dx
drawone:
mov ah,2h
mov dl,bl
int 21h
loop drawone
or bh, bh
jz retorn
mov dl,0Ah
int 21h
mov dl,0Dh
int 21h
retorn:
pop dx
pop cx
pop bx
pop ax
ret
end start
Please, forgive me if I am wrong.
Cheers.
