Narrative:

I was #1 on runway 13R at dal. I was on tower frequency as I did run-up. No contact, ie, he (controller) was not talking to anyone at runway 13R. There was a commercial airliner about 50-100 yards on taxiway moving towards me. I called tower and gave call sign and said 'ready runway 13R.' he said cleared for takeoff. I did. Then he called up on climb out and said the clearance was for the airliner behind me. I had been on tower frequency for over 1 min. He never contacted me or said anything about the airplane behind me. He must not have known the order at the runway. There's no way that the airliner could have taken off without me moving. I was on the yellow centerline at hold short line. He never contacted me about clearing the plane behind me and blocked by me for takeoff. As #1, and hearing 'cleared for takeoff' immediately after I said 'ready runway 13R,' I took off. I must have missed the call sign if he gave it.
