You really don't have enough for a useful snippet. It doesn't do anything! Takes input then terminates!
And you need more comprehensive comments. Something more like...

 Assembly Syntax (Toggle Plain Text) 
       ; Get a character from input with echo in al
    mov ah,1    ; CMD: Get single char 
    int 21h     ; DOS interrupt .
             ; al = char
 
     mov ah,4ch  ; program exit
    int 21h     ; DOS interrupt
       ; Get a character from input with echo in al
    mov ah,1    ; CMD: Get single char 
    int 21h     ; DOS interrupt .
             ; al = char

     mov ah,4ch  ; program exit
    int 21h     ; DOS interrupt
