A procedure can halt its own execution using the stop command:
stop
In this example "goodbye" is never printed:
to print-and-stop
�� print "hello"
�� stop
�� print "goodbye"
end
A procedure can pause for a specified number of seconds using the wait command:
wait SECONDS
In this example "goodbye" is printed 10 seconds after "hello" is printed:
to print-and-wait
�� print "hello"
�� wait 10
�� print "goodbye"
end
A block is a list of commands that are executed in the order they appear:

loop [COMMANDS]
every SECONDS [COMMANDS]
foreach LIST [COMMANDS]
