Well, you didn't include the two results you were getting and which one you though is correct. It always helps if you tell us what you get, we're not omniscient.

Anyway, I refuse to believe this is a OS issue. But what I do believe is that's Perl version issue. Given that the code is in the file x.pl: 

$ /opt/perl/5.8.0/bin/perl x.pl 
<<< 
HTML1
 >>>
<<<  CODE1  >>>
<<< HTML2
 >>>
<<<  CODE2  >>>
<<< HTML3 >>>

$ /opt/perl/5.6.1/bin/perl x.pl 
<<< 
HTML1
 >>>
<<<  CODE1  >>>
<<< HTML3 >>>

$ /opt/perl/5.6.0/bin/perl x.pl 
<<< 
HTML1
 >>>
<<<  CODE1  >>>
<<< HTML2
 >>>
<<<  CODE2  >>>
<<< HTML3 >>>

$ /opt/perl/5.005_03/bin/perl x.pl 
<<< 
HTML1
 >>>
<<<  CODE1  >>>
<<< HTML2
 >>>
<<<  CODE2  >>>
<<< HTML3 >>>

So, it's my guess that the Linux box you tried this on has perl 5.6.1 installed, and the Windows box has either a later or an older version of Perl installed.
