I need to read from a text file that has over 2000 Two-Column entries. What I want is to have the user input a data number, i.e 150, and have a sub-vi search the file for that value and retrieve the associated column with that value. However, since it is a big file, there needs to be an optimized way to search the columns. If I design some logic to "smartly" send the data range to search for, is there a strap on sub-vi that will work in this case, or will I have to modify an existing one from the toolbox?
Thanks, David
