A physical line is a sequence of characters terminated by an end-of-line
-sequence. In source files, any of the standard platform line termination
-sequences can be used - the Unix form using ASCII LF (linefeed), the Windows

-Macintosh form using the ASCII CR (return) character. All of these forms can be
-used equally, regardless of platform.
