Stop
The Stop command is used to stop a flowchart or a procedure. Depending on where it is used it will
have different effects:
Stop at the end of a flowchart – when the program running encounters this command it will simply
stop running the flowchart. If there are other flowcharts running
(multi-tasking) they will continue un-affected.
Stop at the end of a procedure – all procedures must have a stop, without one the program will
eventually fail. When the stop is encountered the procedure will stop
running and return to the place it was called from.
Stop All
This is a special version of the stop command. Whenever this command is encountered it will stop all
procedures and flowcharts immediately i.e. it will stop the whole control program.
In effect this is like an emergency stop, everything will shut down. It is not a ‘graceful’ way for a
program to end, but particularly with younger children it can be quite useful, e.g. to program an
emergency stop.
