Thank you, Jacque. I thought things were not as they seemed and I was reading large files but the line limits would confuse me as to why some times they did not seem to matter like when reading a whole file and putting it in a field but if I converted the file I would need to save the converted text in lines that are 62k or smaller. And yet when I would finally convert it back to the original file it did not need to be save in lines 62k or smaller.
