Having a bit of difficulty getting my input to print once a white space character is inputted. So far, i have it to display the uppercase/lowercase of the input but once i enter a string it doesnt read whats after the white space character. any suggestions?

org 100h
include 'emu8086.inc'
printn "Enter string to convert"
mov dx,20
call get_string
printn
