HI,
i try to explain how to use to LABVIEW TOOLS...

1. USE a for next loop
2. here you must open the file with the VI. read lines from file.
you can choos how many lines you read at same time.
3. the string you can convert into an number.
4. in the loop is the literal counter... this is you line couter....

The exact details of how you do it depend on the file format. There are several file read functions that come with LabVIEW. You might want to start with one of them. If you would attach an example of the file and details of what you need from it, more help could be provided.
