MS-DOS Debug Script

Here is a hello world program in another flavor of dos 80x86 assembly. This debug script should run on any 80x86 machine with a minimum dos version of 3.0 (? - I am not sure when Interrupt 0x21, function 0x9 was introduced.)

a
mov ah,9
mov dx,108
int 21
ret
db 'Hello, World!',0d,0a,'$'
