The output of your code should appear in a separate browser window. 208 <LI>Additional adjustments can be made through the 'Options' dialog. Notably, running CGI (Perl) on UNIX 209 may require changed settings for file permissions and line endings. 210 <LI>Different browsers handle HTML entities in textareas (&gt; etc in the edited code) in different ways. 211 Adjustments for this can be made in the 'Options' dialog. 212 <LI>'Fancy view' shows your code in a colorful way through the built-in PHP source viewer.
