title: Igor Pro, how to convert one text value in a wave to a string
body: <p>This is for Igor Pro, wavemetrics.</p>
  <p>As part of a bigger task I'm trying to complete, I need to take a specific value from a text wave (e.g. wave[i]) and turn it into a string. How can I do this in Igor? My  next step is to use FindValue, and for a text wave I need to provide the exact string to look for. But I want it to go through a text wave one index at a time and look to see if that text is already included in a separate wave. If not, I want it to add that text. If it is, I want the for loop to move to the next index. This seems easy, but I've been struggling all morning!</p>
