Question

Use the following and show the output. Make sure and show the final cursor location.

.data

Msg1 db 'This test is really'
Msg2 db 'hard!'
Msg3 db 13,10,10,'$'
Msg4 db 'I will get an '
Msg5 db 'A',13,'$'

.code

mov ah, 9
mov dx, offsetMsg1
int 21h
mov ah,9
mov, dx offset Msg2
int 21h
mov ah,9
mov dx, offset Msg4
int 21h
mov ah,9
mov dx, offset Msg2
int 21h
mov Msg5, 'F'
mov ah,9
mov dx, offset Msg4
int 21h

Output:

I am pretty positive the output is "This test is reallyhard! hard! hard! I will get an FI will get an A"

However, I am unsure how to get to that answer. I am fairly new to Assembly Language and am not sure how to go about reading this code. What is the print statement? What does offset, int 21h, and mov ah,9 do?
