They can be specific words or numbers, or any given word or number. The concept is used in most coding languages and has many uses.

Reentrancy and Stateful VI's

Whether you’re new to LabVIEW or have been around the block the topic of VI reentrancy is an important one especially when dealing with stateful VI’s. In this post we’re going to briefly define the different reentrancy settings and then talk about the dangers of stateful VI’s who have the wrong reentrancy settings or are used in the wrong context. We define a stateful VI as one that stores data within itself from one call to the next. This is done in LabVIEW using shift registers and feedback nodes.
