Class or object types must always be declared with an explicit type declaration in a type section - unlike record types, they cannot be anonymous.
The main reason for this is that there would be no way you could declare the methods of that type - after all, there is no type name.
program Produce; var MyClass : class Field: Integer; end; begin end.
The example tries to declare a class type within a variable declaration - that is not legal.
program Solve; type TMyClass = class Field: Integer; end; var MyClass : TMyClass; begin end.
The solution is to introduce a type declaration for the class type. Alternatively, you could have changed the class type to a record type.
