IDL, like many computer programs first written in the era of
FORTRAN card decks, uses an 80-column line. (I always have
the idea that people who don't sign their names to newsgroup
posts are young kids who have missed out on far more than just
drugs, sex, and rock and roll from the sixties. They
missed out on etiquette too. Or, at least that is what I
imagine. I'm probably wrong.)
In any case, when IDL is writing data to a file in free-format
mode and it gets to the end of that 80 character line, it just
moves on to the next line, and continues in this manner until
it runs out of things to say.
If you want to make the line wider (sounds like you do), then
you can use the WIDTH keyword to make it as wide as you like:
OpenW, lun, filename, /Get_Lun, Width=180
Cheers,
David
