How to create a hidden text field?

print p("Book Code: ", textfield("book", $bookcode));

How to modify the above code to create a hidden text field?
Or how to make a  variable name "book" to store the value of perl variable $bookcode?

If you using CGI.pm this is the way:

        print $query->hidden(-name=>'hidden_name',

If not then I don't understand the code above... Tell me what your using or show me some more code.  If you want to do it by hand try this:

print qq(<input type="hidden" name="book" value="$bookcode">);

The qq() is just double quotes but you can use this method so as not to have to escape all the double quotes the string may contain.
