This question has been asked and answered many times on the forums. The quick answer is "no", whereas "sentinel" value detection may be sufficient for meeting your specs/requirements.

At this risk of being appearing obtuse and insensitive, I would recommend you perform a comprehensive forum and LabVIEW Help search prior to posting. You're becoming a forum regular, and I would recommend that as you learn from the LabVIEW experts, likewise you attempt to answer questions of forum beginners. Answering other's questions sharpens your skills even more than having your own questions questions answered! Give and take, you know? 🙂 Thanks! -Jack
