1.12 Check structures

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

Supplementary conditions

● Blocks with check structure elements cannot be suppressed.

● Jumper markers (labels) are not permitted in blocks with check structure elements.

● Check structures are processed interpretively. When a loop end is detected, a search is

● It is not generally advisable to use a mixture of check structures and program branches.

● A check can be made to ensure that check structures are nested correctly when cycles

made for the loop beginning, allowing for the check structures found in the process. For

this reason, the block structure of a program is not checked completely in interpreter

are preprocessed.
