Is there any way to override the type of a property? As an example, if

Is there a drop-dead simple way to clone an object?
I've got a small tree of classes (tBaseProfile, and four descendants of
such). Only the descendant classes are instantiated. I need to be able
to create new copies of these objects for use in other lists.
At the moment, I am writing a Dupl

I have objects stored in a dynamic array, and I want to delete an

FPC offers the +=, -=, etc., statements swiped from C. Is there any
reason why ++ and -- are not similarly supported? I know that we have
inc() and dec(), but I'd say that ++ and -- are easier to type.

I have prayed to Google many, many times, but I still cannot find an
answer (or, at least, an answer that compiles). I want to set up a
dirt-simple network client/server pair. So simple that all I do is hurl
bytes into a bucket, and they get transferred to the other side. Does
anyone know of

You can use the sockets library for that.
Examples of sockets programming are available in the internet, mainly in C,
but you can see how it works with that.
I found one that didn't compile. I managed to clean it up, somewhat
poorly, enough for it

Thanks. I'll check that one out.

Not at all. But there is no other reason to use forward-declared

why you might need them.

Absolutely. Because in both of those cases,
