Go Up to Error and Warning Messages (Delphi)

This happens when trying to assign a literal value to a generics data field.

program E2506;

{$APPTYPE CONSOLE}

uses
  SysUtils;

type
  TRec<T> = record
  public
    class var x: Integer;
    class constructor Create;
  end;

class constructor TRec<T>.Create;
begin

  x := 4; // <-- e2506 Fix: overload the Create method to take one parameter x and assign it to the x field.
end;


begin
   Writeln('E2506 Method of parameterized type declared in interface section must not use local symbol');
end.
