Thanks, Bob,
I see this working, too. I did end up with Ben's method, since it required
fewer changes.

Hi Haje,
I ran into this a while ago, I used IDL (on windows) to create
scripts to execute fortan code on linux. If I remember correctly,
I used a writeu,lun statement instead of printf,lun
which did not append the end of line.
You could concatenate the appropriate end of line to your
string buffer, then writeu it to file
Cheers,
bob

I hope this isn't a red herring, but how about...
openw,u,"file.txt",/get_lun & printf, u, "Doughnut", format
='($,A0,%"\r\n")'& free_lun ,u

The only problem I find is that IDL and C format codes do not readily mix.
Can "\r\n" be translated to an IDL format code? H.

Peter,
Thanks for your response. Is this really my only option? I know that I can
also "convert" the file by reading and writing the file in IDL character by
character and replacing the line endings. The problem is that this adds
significant overhead when lots of files 100MB each are written. Therefore I
wanted to write the files correct the first time around. I was wondering if
adding \r\n to the format statement would do the trick?

Hi,
That might be the easiest, but if you have a lot of these to do I
think the C printf kind of formatting allows you to add combinations
of "\f\n" to a line of output.
?printf-style
gets you there.
Cheers,
Ben

You could thug it with a system call from your program to unix2dos (or
whatever utility) after you've finished...
