Actually... none. :)

Hmmm... very nice advice. :)

So, may I conclude that FPC is targetting D7 language compatibility? That's
sound fair enough to me, and -thanks God- I can live with that. :)
Is the D7 compatibility has been reached fully or partially or still under
development? How far the compatibility of FPC v.2.0 with D7? Is there any docs
at least the (com) "implements" keyword and the variant IDispatch compiler support is still missing, whereas someone wanted to tell me the behaviour of the latter, but mysteriously vanished. Someone else started to implement the "implements" keyword, I think.
For IDispatch, its something like if there is a variant (containing a ??? IUnknown reference) used in an expression, and then a dot follows, then pass the actual method name of the method called via idispatch to the interface in the variant.
It's like
i: IUnknown;
v: Variant;
i := mooo;
v := i;
v.Bla; <--- magical auto-"cast" to IDispatch and passing 'Bla' to be
called to "Invoke"
----
HRESULT Invoke(
DISPID dispIdMember,
REFIID riid,
LCID lcid,
WORD wFlags,
DISPPARAMS FAR* pDispParams,
VARIANT FAR* pVarResult,
EXCEPINFO FAR* pExcepInfo,
unsigned int FAR* puArgErr
);
Use GetIDsOfNames or the object's documentation to obtain the dispatch identifier.

Pretty sure I'm missing something (like for example what the dispids and 'dispatch interfaces' are for and such), and it makes no sense if we dont have an user who uses IDispatch (since it then cant be really tested, plus, on linux - where I am -, there are close to no apps that support that IDispatch interface at all). Someone please fill in the gaps.
(Plus, I hated IDispatch when I was using delphi. Very good for variant-based runtime-only errors, hard to track down.)
explain about this issue? Because I still failed to compile my D7 codes under
FPC 2.0. It's an D7 codes utilizing dbExpress components.
Hmm, well, more info please :)
