我用debug跟踪这程序,在执行pop是怎么显示是无效指令?
assume cs:codesg
codesg segment
mov ax,2000h
mov ss,ax
mov sp,0
add sp,4
pop ax
pop bx
push ax
push bx
pop ax
pop bx
mov ax,4c00h
int 21h
codesg ends
end
assume cs:codesg
codesg segment
mov ax,2000h
mov ss,ax
mov sp,0
add sp,4
pop ax
pop bx
push ax
push bx
pop ax
pop bx
mov ax,4c00h
int 21h
codesg ends
end
