Use a CASE statement for this.

case line.upcase
   when 'ADDRESS:'
        $ie.text_field(:name, 'Address1').set(line)
        $ie.text_field(:name, 'Address2').set(line)
        $ie.text_field(:name, 'Address3').set(line)
        $ie.text_field(:name, 'Address4').set(line)
        $ie.text_field(:name, 'Address5').set(line)
        $ie.text_field(:name, 'Address6').set(line)
        $ie.text_field(:name, 'Address7').set(line)
   when 'TESTID'
    # ...
   else
     # raise or what?
end

You can as well create more complex but flexible mechanisms (e.g. look 
up a lambda in a Hash) but whether it's worth the effort depends on your 
needs.
