Unresolved Zoom operations
Zoom operations need to comply with a rule that no other operation can be between Zoom operation and Select operation, corresponding with a Form Control.
In such cases, Zoom operations are not executed.
RM Compatible logic:
In this example, Call Program operation has Flow mode: After. Because Update operation is between the operation and Select operation, Zoom is not executed. Thus the operation is unreachable.
The same principle applies also to Zoom Before operations. If there is another operation between Zoom Before and Select, the Zoom is not executed.
Block with operations with opposite Direction property
In situations where we have Block with Forward Direction and it contains operations in Backward Direction, these operations are never executed. And vice versa, Forward operations in Block Backward..
In this example, all operations within the Block are unreachable, this removed. And in this case, since no other operations are left, also the Block itself is removed.
NOTE: Conversion process removes all unreachable operations!
