Anyone ever hear this from a controller

Did your enroute routing take you over an IAF or feeder fix? If so, you
should have just flown the previously assigned route until you were on a
published segment of the ILS approach.

Steve, I think you are correct. There was no IAF on the plate, but I did
have an assigned heading of 180 from a while back. Once the second
controller cleared me for the approach (as unorthodox as his verbology was)
I probably should have just stayed on a 180 heading until I intercepted the
approach course and then began my descent for glide slope intercept. It was
the unusual way in which I was handled that threw me off.

The only time I've ever heard someone ask for "the full approach" was if it
was NOT Radar Required and there was some sort of course reversal involved
that they wanted to practice.

I just expected to hear, "Ok, Cessna 07G continue heading 180, maintain 2000
until established, cleared for the ILS 15 approach." When I didn't receive
a heading I incorrectly assumed I could fly whatever heading I needed to
intercept the approach course at or prior to the FAF. Technically, I was
given a heading. It was 180. That was my last clearance and no one changed
it so I should have flown my last assigned heading. As others have said,
once I was confused as to the clearance I should have started asking
questions or for clarifications.

Thanks for all your help out there.
