IdTCPServer1Execute

Hello,

I'm a little bit confused with threading in indy.  Is it safe to call in
following manner if I have more than one connection?

procedure TForm4.IdTCPServer1Execute(AContext: TIdContext);
vat tmp_string:string;
begin
tmp_string:=AContext.Connection.IOHandler.ReadLn(#$0a,5);

//some job with tmp_string

end;

What is the best place to ask about indy in delphi?

Thank You
