Stripping Returns

[JB]

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.

You really explained a lot.

Displaying a long line of text will truncate it after 62k but as I understand it, the truncation is visual only.  If a script asks for the line it is all returned. (Better check that, but that was my understanding.)
