All good advice, but unfortunately the poster is constrained by the fact that ReadParse is part of CGI.pm. And the author of CGI.pm was constrained by the fact that ReadParse was written to be a drop-in replacement for the function of the same name from cgi-lib.pl. If you're interested, the code in CGI.pm looks like this:

sub ReadParse {
    local(*in);
    if (@_) {
    *in = $_[0];
    } else {
    my $pkg = caller();
    *in=*{"${pkg}::in"};
    }
    tie(%in,CGI);
    return scalar(keys %in);
}

Of course, ReadParse was only included in CGI.pm to ease the transition of moving code from cgi-lib.pl to CGI.pm. There's no reason at all why people should be using it these days. If you want to get a hash containing all the parameters (which is kind of what ReadParse does), then CGI.pm provides the far simpler and more flexible Vars function. And in most cases, you probably just want to be using param anyway as others have mentioned.
