Begin by renaming your formats to match the currently selected output stream, which is STDOUT by default:

format STDOUT_TOP =
MANUFACTER----MODEL
.

format STDOUT =
@<<<<<<<      @########
$key,          $value
.

Once that works, read perlform for information on how to define multiple formats and how to change them for the currently selected output stream. If you want to continue to use the names you have, try this:

use English;  # less line noise ;-)
$FORMAT_TOP_NAME = 'HEADER';
$FORMAT_NAME = 'FLOR';
