nun ja, ich arbeite mit W10 und möchte den Perl-Interpreter nicht unbedingt installieren, da ich ihn ohnehin nicht oft benötige, aber mit dem experimentieren auf der Konsole hast du natürlich grundsätzlich recht.
Es gibt Strawberry Perl als Portable (nur für dich als Nutzer, kein Install nötig) ⇒ https://strawberryperl.com/releases.html

Na ja, wahrscheinlich kann man das "Layout" noch verbessern:

Um die Daten von Kunden, Produkten und Aufträgen zu organisieren, eignen sich übrigens Objekte wunderbar. Ich würde die Daten also so organisieren. Allerdings liefert die Dein Programm leider nicht so, das ist also nur theoretisch. Aber wäre schon cool:

Und hier noch eine "Deluxe-Version". :)
Man kann dann z.B. die Aufträge ("order") direkt zu den Kunden ("customer") speichern:
