You can use heredocs:

print <<'END_HTML';

<h1>this is a big piece of text sent to the browser</h1>
END_HTML

I posted something that used heredocs extensively not too long ago. The documentation is in perldoc perldata.

I'm not quite sure this is what you wanted, but your post wasnt very clear.

update

: you could use heredocs like so:

$array_of_pages[0] =<< 'LABEL';
# your html code goes here
LABEL
$array_of_pages[1] =<< 'LABEL;
# your other html code goes here
LABEL
# ... and so on

# directly from perldoc perldata...
           ($quote = <<'FINIS') =~ s/^\s+//gm;
               The Road goes ever on and on,
               down from the door where it began.
           FINIS

this is what Quinn1981 seemed to be asking me in the CB.
