Compilation: Determining whether two strings are equal to __ assembly

To determine whether two strings are equal output match or no match

Assume Cs:code,ds:data

Data segment

String1 db DUP (0)

string2 db DUP (0)

String3 db ' Please input string 1-by-space ', 0dh,0ah, ' $ '

String4 db 0dh,0ah, ' please input string 2-by-space ', ' $ '

String5 db 0dh,0ah, ' match$ '

String6 db 0dh,0ah, ' no match$ '

Data ends
