3．已知在以ARRAY为首地址的数据区中存放5个带符号字数据：
ARRAY DW 1,-2,-1,3,4
编程将ARRAY分成两个数组：正数数组P_ARY和负数数组N_ARY，并分别显示正数项个数和负数项个数。

要代码

Answer 1

data segment
ARRAY DW 1,-2,-1,3,4
P_ARY DW 5(?)
N_ARY DW 5(?)
count DW 0
data ends

code segment
main proc far

assume cs:code,ds:data
start:
mov ax, ds
push ax
mov ax,0
push ax

mov cx,5
mov di,offset ARRAY
mov si,offset N_ARY
lea bx,P_ARY

again:
mov ax,[di]
cmp ax,0
ja positive
inc si
mov [si],ax
jmp next
positive:
inc bx
mov [bx],ax
next:
inc di
loop again

sub di,offset N_ARY
mov N_ARY,di
sub si,offset P_ARY
mov P_ARY,si

ret
main endp
code ends
end start
