Using Express Write LabVIEW File to store data in subprogram doesn't overwrite.

[BLeffler]

The main program is an Event Structure that controls four other subprograms. In the subprograms the data is stored in the express IV Write LabVIEW Measurement File set up to overwrite the collected data. When the subprogram is stopped with the main still open, then restarted, the file is appended not overwritten. It appends where the last time the previous file was stopped.

There is an input to the Wrive LabVIEW Measurement File which is entitled 'reset.' Make sure that is set to true so that the file writing process starts over each time data enters the Express VI.
