s is the real problem... I have a data file that I want to open and read into an array then merge it with a brand new data file to start a database or to a database if one is already created. I have started the VI but it doesn't seem to work. Thanks again.Well, if i understood you well, the problem is to merge two arrays with new data everytime it is created, attached there's an vi that will do that, if you wire your first array to the shift array input, your array generation vi to the true case state, and the write vi to the shift array output, it's done. Sorry but couldn't see the example you sent (I only have LV 5.0) if you have some kind of problem or comment, send it.
Hope this helps
