微机实验代码

微机实验代码1：

data segment
  org  2000h
  num1  db   12h,95h,0f1h,0c2h,82h,2h,10h,34h
  count equ   $-num1
  org  3000h
  num2  db    23h,0dfh,023h,3fh,3ch,0b3h,57h,3h
  org  5000h
  res   db    count dup(0)
  data  ends

微机实验代码2：

MOV   AX,WORD PTR [FIRST]
ADD    AX,WORD PTR [SECOND]
MOV  WORD PTR [THIRD],AX
MOV   AX,WORD PTR [FIRST+2]
ADC    AX,WORD PTR [SECOND+2]
MOV  WORD PTR [THIRD+2],AX
