  .CODE

  MOV AX,@DATA

  MOV DS,AX

      ;DISPLAY PROMPT

      MOV DX,OFFSET PROMPT
    
      MOV AH,9
    
      INT 21H
    
      ;INITIALIZATION
    
      MOV CX,3    ;LOAD COUNT INTO CX
    
      MOV BH,0    ;BH=0 TO HOLD MAX
    
      MOV AH,1    ;PARAMETER FOR INT 21H
    
      ;PROCESSING..
    
  NEXT:

      INT 21H     ;READ NUMBER
    
      MOV BL,AL   ;SAVE NUMBER TO BL
            
      CMP BL,BH   ;COMPARE NUMBER WITH BH, ASSUMING THAT BH HAS MAX
    
      JLE SKIP    ;IF BL IS LESS THAN OR EQUAL TO BH, THEN SKIP
    
      MOV BH,BL   ;ELSE BL HAS A BIGGER VALUE AND COPY IT INTO BH
    
  SKIP:

      LOOP NEXT   ;REPEAT TILL CX=0 AND ONCE THE LOOP IS DONE, BH WILL HAVE MAX
    
      ;PRINT NEWLINE
    
      MOV DX,OFFSET NL
    
      MOV AH,9
    
      INT 21H
    
      ;PRINT MAX VALUE
    
      MOV DL,BH
    
      MOV AH,2
    
      INT 21H
    
      ;PRINT THE MESSAGE IS THE MAX VALUE
    
      MOV DX,OFFSET OUT1
    
      MOV AH,9
