I solved the issue another (even simpler) way, which even solves the
issue of different line break codings on different platforms.
Pity that I didn't think of that before ;-)
nLineLength = string.len(line)
if string.sub(line, nLineLength-3, nLineLength) ~= "<BR>" then
line = line .. "<BR>"
But your ideas were necessary to lead me to this solution. So thanks a lot!
