The LOOP command is at the end of the loop for Repeat loops. As soon
as one stop criterion is fulfilled (case 2), the command after the LOOP com-
mand is carried out. If no stop criterion is fulfilled, (case 1), the loop is run
through again. In either case, the loop is run through at least once.
The LOOP command is at the beginning of the loop for While loops. If the
arrow has been dragged to a command after the LOOP command, another
arrow is automatically set from the previous command back to the LOOP
command. As soon as one stop criterion is fulfilled (case 2), the command
after the loop is carried out. If no stop criterion is fulfilled, (case 1), the loop
is run through. It is possible with certain stop criteria that the loop is never
run through.
Note
Nested and overlapping loops are not allowed.
