Darnell:
As I mentioned in a post to another one of your questions, since you are reading a text file, you have very little reason to read a text file one character at a time.
Why not read one line at a time and parse each line one at a time?
Look at the ChillerParser.zip project I posted to your question here: http://forums.ni.com/ni/board/message?board.id=180&thread.id=42623
Take another look at the RunCallback function in ChillerScript.c.
Also note that your OPEN_TEXT_FILE function will generate a runtime error if your file has more than 250 bytes.
