1. line terminator
What is the normal line terminator for ascii files (dos/win) CR, LF or both?
I had a bug and found that the last line in the file had no CR, LF but
all the other lines had a CR. I'm wondering if I ported the files
incorrectly from brand x operating system. (Theos OS).

I have found it is best to always check every file you read (unless you wrote
it in an Eu program) for which combination of line terminators. A text editor
may save it one way, a browser another way, any webpage may be
backwards, the OSs are different, the option of the ftp downloader may
change the file, etc etc. I never parse on \n anymore, i always parse on
{10,13} now. Also, when you use Eu to open a file for reads or writes, save
yourself some grief and use the "b"(inary) option.

Hi George,
integer crlf
if platform() = LINUX then
crlf = 10
else
crlf = 13
end if
just a thought...perhaps there's more to this

The last line of a file does not always have a line terminator.
Create a file in say notepad: Just enter "hello", - but do not key
return - and there will be no CR's or LF's anywhere in that file.

It's my understanding that DOS/Windows uses the combination 13-10, unix
uses 10, and Macintosh uses 13. This applies to all lines except the
last one. The line terminator is optional for the last line. Additionally,
DOS/Windows may follow the last line with 26.
A few things to remember though:
** Not everyone follows this convention perfectly.
** Euphoria deals with this detail internally and always replaces
13-10 combinations with just a 10 for you.
** Some text files read on one operating system may have been created
on another.
If you don't know exactly how the file was created, open it in binary mode
and then assume any combination of CR & LF terminates a line, and that
the last line might not have either CR or LF.
