Hello all,
to get address of function I can use @MyFunction, but if I use it within
MyFunction - I get address of Result. How can I get address of current
function? (It's not for assigning to something else. It is for a kind of
self modifying code.)
Regards

@unitname.function (or @programname.function if you are in the main program
file)

Hi!
You can use WriteStr to "Writeln" to a String (needs 2.4.0 and above).
Example:
var
s: String;
begin
WriteStr(s, 'Hello World');
end;
Also you can try unit StreamIO (in fcl-base) which allows you to use
Streams as TextFiles (you can also look at it to learn how to implement
your own
Hi again!
I forgot to mention:
If you want to redirect StdOut (or Output as the variable is called in
Pascal) you need to assign a new TextFile to Output (but keep the old
one around and assign it back later when your application is terminating).
Example:
var
oldoutput, f: TextFile;
begin

This looks more promising, streams seem to be a more high level
implementation of such concepts. I'm cur

But I do not understand the following:
function TStream.Write(const Buffer; Count: Longint): Longint;
what type is Buffer? How does it get away with the missing type
declaration without the compiler failing to compile this at all?
Quote from the Docs (
If I have a class with a property Phase: TrrPhase where TrrPhase is an
enumeration such as (rrQuiescent, rrInitialised), is there an elegant
way of extending the enumeration and overriding the property type so
that a derived class can use the new values?

As far as I know, properties cannot be overridden. However, you could
consider using subrange types, as the example below shows.
type
Fruit = (Apple, Banana, Cherry, Orange, Pineapple);
LimitedFruit = Apple..Cherry;
You can use the full enumeration as the property's type, and then
restrict i
OK, I got it working now. Just in case somebody else is googling for
something like this:
first I define a class TDebugStream that will later replace the standard output:
Type
TDebugStream = class(TStream)
function Write(const Buffer; Count : Longint) : Longint; override;
end;

Yes, you are of course right, this is simpler. I just forgot to
simplify it after I was initially playing around and experimenting
with a separate file and without

Can i ask to be an "Feature Request" in FPC?
