Controller assigned another heading, but didn't tell flight crew that it canceled the airway intercept, so when flight crew intercepted and turned, controller told them they were supposed to remain on the last heading.

Narrative:

During climb phase out of pvd we were told to head 285 degrees to intercept J77. Then we were told to turn right 5 degrees to intercept J77. We were then given a frequency change. We were then given a heading of 280 degrees. Very shortly after intercepting J77, center asked our heading. I responded with our heading (about 265 degrees) and said 'our last clearance was 280 degrees to intercept J77. The controller said 'I gave 280 degrees for your climb.' 'return to 280,' (which we did). The controller failed to inform us of our canceled intercept clearance. Clear language such as: 'traffic at 10 O'clock position, 12 mi, maintain heading 280 degrees for climb, clearance back on course in 2 mins' clearly denotes, 1) canceled clearance, 2) obvious expect further clearance time, and 3) location of conflicting traffic.

Original NASA ASRS Text

Title: MLG ACFT IN CLB AND ON HEADING VECTORS TO INTERCEPT AIRWAY. CTLR ASSIGNED ANOTHER HEADING, BUT DIDN'T TELL FLC THAT IT CANCELED THE AIRWAY INTERCEPT, SO WHEN FLC INTERCEPTED AND TURNED, CTLR TOLD THEM THEY WERE SUPPOSED TO REMAIN ON THE LAST HEADING.

Narrative: DURING CLB PHASE OUT OF PVD WE WERE TOLD TO HEAD 285 DEGS TO INTERCEPT J77. THEN WE WERE TOLD TO TURN R 5 DEGS TO INTERCEPT J77. WE WERE THEN GIVEN A FREQ CHANGE. WE WERE THEN GIVEN A HDG OF 280 DEGS. VERY SHORTLY AFTER INTERCEPTING J77, CTR ASKED OUR HEADING. I RESPONDED WITH OUR HEADING (ABOUT 265 DEGS) AND SAID 'OUR LAST CLRNC WAS 280 DEGS TO INTERCEPT J77. THE CTLR SAID 'I GAVE 280 DEGS FOR YOUR CLB.' 'RETURN TO 280,' (WHICH WE DID). THE CTLR FAILED TO INFORM US OF OUR CANCELED INTERCEPT CLRNC. CLR LANGUAGE SUCH AS: 'TFC AT 10 O'CLOCK POS, 12 MI, MAINTAIN HDG 280 DEGS FOR CLB, CLRNC BACK ON COURSE IN 2 MINS' CLRLY DENOTES, 1) CANCELED CLRNC, 2) OBVIOUS EXPECT FURTHER CLRNC TIME, AND 3) LOCATION OF CONFLICTING TFC.
