I use a SuperWebApp module as the base for applications, as described in 
the documentation.

This can be used to get and set global items:

$self->param(
        username  => $username,
        host      => $host,
);

later . . .

print $self->param('username');


CGIApp uses CGI.pm, so I get at the form or query data when I need it 
with this (in SuperWebApp.pm)

sub vars {
    my $self = shift;
    return $self->query->Vars;    #ref to cgi params hash
}

It avoids some confusion (for me) to be consistent in naming the params 
from CGI.pm  "$vars" as in
  my $vars = $self->vars;

HTH,

Bruce
