<p><a name="index-PreserveCR-158"></a>
Syntax: <code>PreserveCR [0|1]</code><br>
Abbreviation: <code>PCR</code>

<p class="noindent">sets the preserve carriage returns flag.  When a file is
loaded into a buffer for which this flag is false, both CR (carriage
return) and NL (new line) characters are treated as line terminators. 
If the flag is true, CR characters do not act as line terminators but
are instead preserved in the buffer. This flag has no effect except
when loading a file into a buffer.

   <p>If you invoke <code>PreserveCR</code> with no arguments, it will toggle the flag. 
If you specify 0 or 1, the flag will be set to false or true,
respectively. An upper case &lsquo;<samp><span class="samp">P</span></samp>&rsquo; will appear on the status bar if the
flag is true.
