I hope I don't seem too dense, but I'm still not clear on why a script 
would need to replace line endings manually this way. I'd like to 
understand it. When would a simple replacement with the "return" 
constant not work?

For example, in Kee's problem, I'd think that this would work okay:

   get data from database, put it in a variable
   replace database line endings with returns in the variable
   put variable into a field

It seems to me that the above would convert all line endings to 
machine-specific line endings without any manual manipulation, and would 
go cross-platform without any changes. When the data needs to go back to 
the database:

   put the field text into a variable
   replace returns with database-specific line endings
   send variable back to the database

What am I missing? Doesn't this work?
