I know...
Only a newbie wouldn't know that you couldn't print
out the result of a arithmetic operation directly to the screen.

mov ah,6
mov dl,6
add dl,ah
mov ah,02h ; WHY NOT PRINT OUT 12 TO SCREEN, IM NEWBIE
int 21h

why not try adding ah to dl and viceversa using runtime code modification?

start:
zaddz db 00h,e2
xor byte [zadda],2
