From perldoc CGI:
A Lurking Trap! Some of the form-element generating methods
return multiple tags. In a scalar context, the tags will be
concatenated together with spaces, or whatever is the current value
of the $" global. In a list context, the methods will return a list
of elements, allowing you to modify them if you wish. Usually you
will not notice this behavior, but beware of this:
printf("%s\n",end_form())
end_form() produces several tags, and only the first of them
will be printed because the format only expects one value.

Perl snippet question:
---------------------------------------------
#!/usr/bin/perl -w
use strict;
use CGI;
use CGI::Carp 'fatalsToBrowser';
my $new_page = new CGI("");
sub HTMLendFORM ($) {
my $new_page = $_[0];
print $new_page->end_form;
}
HTMLendFORM ($new_page);
print "\n\n";
---------------------------------------------
This above code produces "<div></div></form>". This ti me is odd,
since i only really want </form>. Does anyone have an explanation
or another way to use the CGI.pm library and produce only </form>.
Yes I could just use a print statement. But I am kind of curious to
why?
