Narrative:

While taxiing out for takeoff; we tried to contact queue. There was no response. We then questioned ground about queue and he told us that queue was not in operation. Since the beginning of dfw RNAV departure program; no queue without runway and first fix information has always meant no RNAV procedure. After takeoff runway 18L; we flew a heading which we thought was assigned. The heading was either runway heading or close to it. Exact heading flown cannot be recalled. During the climb out on this heading; we heard the departure controller clear an aircraft to turn right which put this aircraft on a crossing course with us. At that point we realized something was not correct. We were about to question the controller when he asked if we were going to make our turn to the west. We then advised him we were not on the SID and flying the southernly heading. He instructed us to fly 290 degrees ands stop our climb; which is what we did. There was no TCAS warning or alert. The rest of the flight was normal.
