title: Why do we use 10,13 in message DB 10,13, 'foo $'?
body: <p>Here is the Code written on assembly language for 8086 microprocessor.This code find if the number is positive or negative. I understand the code but can not understand the 4th and 5th line of that code.</p>
  
  <pre><code>       ;FIND A NUMBER THAT WAS POSITIVE OR NEGETIVE 
         DATA SEGMENT 
         X DW 28H
         MSG1 DB 10,13, 'NUMBER IS POSITIVE $'
         MSG2 DB 10,13, 'NUMBER IS NEGETIVE $' 
         DATA ENDS 
  
         CODE SEGMENT
         ASSUME CS:CODE, DS:DATA
         START: 
         MOV AX, DATA
         MOV DS, AX
         MOV AX, X 
         ROL AL, 01H
         JC NEGA
         LEA DX, MSG1
         JMP LAST
  
         NEGA:
          LEA DX, MSG2
  
          LAST:
              MOV AH, 09H
              INT 21H
              MOV AH,4CH
              INT 21H 
  
  
         CODE ENDS
     END START
  </code></pre>
  
  <p>Why they use 10,13 after MSG1 DB in the 4th and 5th line ?</p>
