The FOREACH statement repeats block of instructions for each element in an array, list or collection. The foreach statement is used to iterate through the collection to get the information that you want, but can not be used to add or remove items from the source collection to avoid unpredictable side effects. If you need to add or remove items from the source collection, use a FOR loop.

The embedded statements continue to execute for each element in the array or collection. After the iteration has been completed for all the elements in the collection, control is transferred to the next statement following the FOREACH block.
At any point within the FOREACH block, you can break out of the loop by using the BREAK keyword, or step to the next iteration in the loop by using the CONTINUE keyword.

buDescription of attached example:/u/b
There are two nested FOREACH cycles.
First loop iterate through all branches of stirrups. Second loop iterate through all points of that branch.
Note, that iterator variable "obBranch" is used as a source for second loop.
