 REM The FUNCTION command defines a new function named COUNTDOWN() containing a code block with a WHILE loop which types a single period (".") for each value of $TIMER.
 REM The first time the COUNTDOWN() function is called, the $TIMER variable holds the value 3. The second time it is called, the $TIMER variable holds the value 5.
