E2020 Object or class type required (Delphi)

Go Up to Error and Warning Messages (Delphi)

This error message is given when the syntax 'Typename.Methodname' is used, but the typename does not refer to an object or class type.

program Produce;
type
  TInteger = class
    Value: Integer;
  end;
var
  V: TInteger;
begin
  V := Integer.Create;
end.

Type Integer does not have a Create method, but TInteger does.

program Solve;
type
  TInteger = class
    Value: Integer;
  end;
var
  V: TInteger;
begin
  V := TInteger.Create;
end.

Make sure the identifier really refers to an object or class type - maybe it is misspelled or it is hidden by an identifier from another unit.
