Is there a "complete" list of reference counted variables in FP? e.g.

My use case is:

MyListView.Item[0].Data = p;
MyListView.Item[0].Delete; <-- Do I need t
I vote for Traits. This will make FP more flexible... As a matter of
fact, I was surprised to see operator overloading being implemented in
pascal, which was a feature I like in C++, although I have never write a
program more complex than cout << "Hello World" in that magnificent
language. :-)

The document said it is "deprecated"? Also, I want this to be cross
platform, not for unix only. The use case is:
try
buf := GetMemory(1024);
size := 10240;
stream.Read(buf^, size);
except
??
end;

I don't know if it is possible, but how about using fpSignal()? See

I would more call it "Traits" which is at least a feature I'd like to
research. This means that I'll implement it in

And what is interesting, is that FP Text IDE (which looks like Turbo
Pascal IDE) defaults to the .pas extension when creating new units. You
would think being so closely related to Free

Problem solved!
I had a program unit named m2compiler.lpr, and in another directory I
had a unit named M2Compiler.pas. This caused the conflict at linking.

I am using "pas" for units that Delphi compatible you can compile it with
Delphi, now "pp" it is only FPC compiled not compatible with Delphi.

So, it is even OK to use SetLength() on static arrays? interesting.

It will be Nil. An equivalent alternative would be:

Hi All,
I have two simple questions:
1) As far as I know class variables in FPC are automatic initialize to the
NULL value (e.g. 0 or "" or whatever), does that include dynamic arrays?
e.g.
TMyClass = class
myarray: array[0..100] of Integer;
end;
will myarray be initialized to nil?
2) Aft
