If you declare something like
Type
NewString = Record
Data: Array of Char;
End;
And a function:
Function ToNewString(a: String): NewString;
Begin
SetLength(Result.Data, Length(a));
Move(a[1], Result.Data[0], Length(a) * SizeOf(Char));
End;
; The compiler should generate an error when you try to typecast a
String to a NewString.
