Imagine you wanted to write the output as a perl print statement: you could write: 
  my $name = "Dave";
  my $user = "dpuu";

  print <<HERE;
Hello, my name is $name
and my user name is $user
HERE

This will do variable interpolation on a set of lines.

If you want to separate the script and the flat-file, you can create a print-statement on the fly, using eval: 

  my $name="Dave";
  my $user="dpuu";
  my $text_file="User.htm";
  my $text=`cat $text_file`;
  eval "print <<HERE;\n$text\nHERE";

You want to be careful when putting this in a production environment: executing data files as code could introduce some security holes (or just very strange bugs). This script won't work with perl's -T option --Dave.
