The REPEAT loop is executed once and repeated

continuously until the condition is fulfilled.

Nesting depth

Check structures apply locally within programs. A

nesting depth of up to 8 check structures can be set

up on each subprogram level.

Runtime response

In interpreter mode (active as standard), it is

possible to shorten program processing times more

effectively by using program branches than can be

obtained with check structures.

There is no difference between program branches

and check structures in precompiled cycles.
