Allow me a stupid question: how to convert an integer to enum with range
checking? A cast does not generate range checking, if I am not mistaken:
program Project1;
type
TEnum = (one, two);
{$R+}
var
I: Integer;
E: TEnum;
begin
I := 2;
E := TEnum(I); // <<< I want a range check error here
Writeln(Ord(E));
end.
