Very cool! Next step: Make it more discoverable by placing an
index.html or whatever index you need to place at
http://live.freepascal.org/?assignment=assignments or
http://live.freepascal.org/assignments . A person unfamiliar with your
website needs to be able to random access all assignments.

Once again, this is a great way to gently introduce Pascal and show
that it's not some ancient difficult language. Congratulations on a job
well done!
