Mac vs PC .csv files

[Dennis Brown]

Good day to everyone,

I have been ask by a friend on a PC to send him some files in .csv  
format.  When I do, he complains that the returns are missing.  I  
guess I am still a bit unclear on this difference between platforms.   
As I understand it the Mac uses LF for a delimiter, and the PC uses  
CR.   When I end the lines with return, it does not end up as a CR in  
the output file.  Is there a simple way to specify an end to my lines  
that is compatible with all platforms for .csv files that are read by  
programs other than Rev?

Thanks,
Dennis
