[fpc-pascal] How are Assigned, Free, Nil and Destroy related?

[Frank Church]

This is one question I have wanted to ask for a long time.

How are Assigned, Free, Nil and Destroy related, and when is one or another
appropriate? What other procedure have I missed?

There are so many articles and mailing list threads on this issue that I
don't think asking it makes me sound like a newbie, or does it?
