Question

I just can t remember those   So  what is the right way to properly terminate old fashioned ASCII lines

User · Answer

if you are using C   why not using Environment NewLine    i assume you use some file writer objects    just pass it the Environment NewLine and it will handle the right terminators

If you are using C  you should use Environment NewLine  which accordingly to MSDN it is      A string containing   r n  for non-Unix platforms  or a string containing   n  for Unix platforms

In any  NET langauge  Environment NewLine would be preferable

r n   Odd to say I remember it because it is the opposite of the typewriter I used  Well if it was normal I had no need to remember it     -      Image from Wikipedia  In the typewriter when you finish to digit the line you use the carriage return lever  that before makes roll the drum  the newline  and after allow you to manually operate the carriage return    You can listen from this record from freesound org the sound of the paper feeding in the beginning  and at around -1 03 seconds from the end  after the bell warning for the end of the line  sound of the drum that rolls and after the one of the carriage return

From Wikipedia   you can read which is correct for your OS at that article       Systems based on ASCII or a compatible   character set use either LF  Line   feed    n   0x0A  10 in decimal  or CR    Carriage return    r   0x0D  13 in   decimal  individually  or CR followed   by LF  CR LF    r n   0x0D0A

Be careful with doing this manually  In fact I would advise not doing this at all   In reality we are talking about the line termination sequence LTS that is specific to platform     If you open a file in text mode  ie not binary  then the streams will convert the   n  into the correct LTS for your platform  Then convert the LTS back to   n  when you read the file   As a result if you print   r n  to a windows file you will get the sequence   r r n  in the physical file  have a look with a hex editor    Of course this is real pain when it comes to transferring files between platforms   Now if you are writing to a network stream then I would do this manually  as most network protocols call this out specifically   But I would make sure the stream is not doing any interpretation  so binary mode were appropriate
