Fall-through specifically refers to the behavior of switch...case statement in C, C++, and other languages, where execution will fall through from one case statement to the next unless specifically stopped. It's an often useful feature which can lead to bugs.
One definition found online: "Fallthrough: when a state machine can move to subsequent states in the same program cycle."
(So fallthrough could also occur in ladder logic, etc.)
When I Google "flow-through" I get pages of results about pilots, airlines, and training.
Flowthrough may be more correct, though personally I consider fall-thru & flow-thru to be equivalent. But hey, I'm a self-taught hack who makes his own rules and terminology.
