Here is an idea:

Code:
 
$label="   This is a test to see what will happen"
? $label
sleep 3
for $i=1 to len($label)
  chr(8) 
next
"X"


Basically, all this is doing is displaying the LABEL, waiting a few seconds, then pressing the backspace key the same number of times as the length of LABEL, and then adding the "X" (checkmark).
