TThread.CreateAnonymousThread

[Pe3s]

Hello, for using TThread.CreateAnonymousThread thread
Is there any configuration required.
How can I improve the code ?

Code: Pascal  [Select][+][-]

1. procedure TForm1.FormCreate(Sender: TObject);
2. begin
3.   TThread.CreateAnonymousThread(
4.   procedure
5.   begin
6.      // code
7.   end
8.   ).Start;
9. end;        
10.  

Code: Pascal  [Select][+][-]

1. unit1.pas(325,3) Error: Illegal expression
2. unit1.pas(326,3) Error: Syntax error, ")" expected but "BEGIN" found
3.

Probably anonymous functions should be enabled by modeswitch. Try putting {$modeswitch ANONYMOUSFUNCTIONS} in your unit.

{$modeswitch ANONYMOUSFUNCTIONS}

From which version did this become available ?

I use: Lazarus 3.4 and FPC 3.2.2 and get a warning:

Warning: Illegal compiler switch "ANONYMOUSFUNCTIONS+"

It is only in trunk/main.
Better than createanonymousthread is simply executeinthread.
I gave an example some weeks ago:
https://forum.lazarus.freepascal.org/index.php/topic,68823.msg532746.html#msg532746

And can be simplified further.
In 3.2.x this is only possible by taking a function pointer instead.
