Question

Write a program in assembly language that will read in 4 integers and compute (A - B + C - D). Print out the integers with the result.

--I'm not sure if I'm doing my arithmetic properly (most likely not) but I don't know how to output correctly so I'm not sure how to check it. Any help with this would be appreciated.

.data
myMessage BYTE "Please enter 4 integers:",0dh,0ah,0
ResultMsg BYTE "Result: ",0
Num1           DWORD ?
Num2           DWORD ?
Num3           DWORD ?
Num4           DWORD ?

.code
main PROC
    call Clrscr

    mov edx,OFFSET myMessage
    call WriteString

    call ReadInt
    mov Num1, eax

   call ReadInt
   sub eax, Num2

   call ReadInt
   add Num3, eax

   Call ReadInt
   sub Num4, eax

    mov edx,OFFSET ResultMsg
    call WriteString
    call WriteInt

    call CRLF

    exit
main ENDP

END main
