汇编-ADC带进位加法

 ADC(带进位加法) 指令将源操作数和进位标志的值都加到目的操作数中。该指令的格式与ADD指令一样， 且操作数的大小必须相同：

 

.386  
.model flat,stdcall 
option casemap:none
.stack 4096

Include Irvine32.inc
includelib Irvine32.lib

ExitProcess PROTO,dwExitCode:DWORD  
 
.data       

 
.code   
main PROC   
    
    mov dl,0
    mov al,0FFh 
    add al,0FFh 
    adc dl,0  ;dl=dl+0+CF
    ;dl=01h    al=FEh

    
    quit:
    mov eax,[esi]
    INVOKE ExitProcess,0  
main ENDP
