Question

Is it possible to write a method which takes any ordinal type as a parameter? The same way Inc() or High() do?

I’m using Delphi 2007

Answer 1

You’d need to use an untyped parameter:

procedure Foo(const ordinal);

or

procedure Foo(var ordinal);

Of course, you are somewhat limited in what you could do inside such a routine because you have abandoned the type system.
