I've found this thread very helpful, and have changed it to use Vars (from
http://users.easystreet.com/ovid/cgi_course/) as I need a hash. This has
replaced the following:
foreach $entry (param()) {
$fieldhash{$entry}=param($entry);
Checkentry(param($entry));
}
with:
my $q=new CGI;
my %fieldhash=$q->Vars;
which is much neater. My subroutine "Checkentry" untaints the input. Is
there an easier way which will allow the hash values created by Vars to be
passed to my subroutine without stepping through a "foreach" loop?
If I understand correctly then you want a hash reference to pass the
whole hash around at once.

Should help, C<Vars> understands its context, so calling it in scalar
context will result in it returning a hashref instead of a hash.
my $params_ref = $q->Vars;
