On Windows, File.writeln() will append either "\n" or "\r\n" depending on how the file was opened. If it was opened in text mode (the "t" open flag), then "\r\n" is used.
On Linux, the "t" open mode flag is ignored and File.writeln() will always save the text with "\n" appended. Example:
var f = new File("test.blah");
f.open("w");
f.writeln();
Creates a file with a single byte:
$ hd /sbbs/ctrl/test.blah
00000000 0a |.|
00000001
If your edited file is ending up with CRLF terminated lines, that could just be the function of the console.editfile() method (if you're using that) and the underlying C++ methods that post-process the edited the file.
