asterisk users - Jan 2010 - How to recieve number returned by $AGI->wait_for_digit($timeout)

hi,

i use $AGI->wait_for_digit($timeout)  to wait for the user press key 1
,and then to do something.

but how can i get the return number ?

is that use $key = $AGI->wait_for_digit($timeout)

and $key will be "200 result=49" if i pressed number 1?

Thanks!

$key = $AGI->wait_for_digit($timeout);

if (chr($opt) eq '1') {
  # do stuff..
}
