Another easy example would be.

include get.e 
 
constant ESC = 27 
 
integer key 
key = get_key() 
 
while 1 do 
 if key = ESC then 
      exit 
 end if 
end while 

This will end the program when you press ESC. Check the key.bat for list of keycodes.

You could also use wait_key() instead of get_key() in that example, which would wait gracefully rather than polling continuously.

is there a way to set a time limit or have it randomised

You'd have to write your own input function that uses get_key() to watch for keyboard and collect it in a sequence, while also monitoring the time passed since it started monitoring. Then when the time passed a certain point, it would exit its loop and continue on.

Or have what randomized? The input from the user? The time limit?

get_key() and wait_key() only return the key pressed:

integer key 
 
key = wait_key() 
printf( 1, "%s\n", key ) 

So if I press the 'K' key, that would simply output:

K
