When using "int 21h", on MASM Visual Studio Assembly Language, it gives me an error


The error it displays: Unhandled exception at 0x0029101F in AddingAndDisplay.exe: 0xC0000005: Access violation reading location 0xFFFFFFFF. occurred

What I want to do: Add two numbers and display them.

My Code:

INCLUDE Irvine32.inc
main PROC
mov bl, 1
mov cl, 2
add bl, cl
add bl, 48 ;since 48 = 0 in Ascii code, we have to make it equivilant.
mov dl, bl
mov ah, 2
int 21h

mov ah, 4ch
int 21h

main ENDP
END main
