Narrative:
The problem occurred during a runway change. Improper or incomplete coordination by the supervisors regarding the status of dal departure/arrival flow. Air carrier xab departed dal (runway 13R) and was in immediate conflict with another air carrier X jet (call sign was possibly clearance delivery, arriving runway 31R). As soon as I saw the conflict, I called traffic and turned air carrier xab, but not before separation was lost. Supplemental information from acn 571788: I was then attending to other traffic when a supervisor asked if I was 'still talking to air carrier X 737.' I saw the problem, another air carrier X (aircraft #2) had departed runway 13R and was runway heading parallel to the air carrier X. I had cleared for runway 31R. I instructed air carrier X to turn right to 360 degree heading and cancel his approach clearance. He asked why, and I informed him of his company traffic. He replied that he had his company in sight. I told him to maintain visual separation from his company and cleared visual approach to runway 31R. His company turned sbound left to the air carrier X B737 I was talking to and was no factor. Separation was always maintained, but the whole procedure was careless, slipshod, and basically stunk. Many things went wrong. As always, the pilot(south) should be complimented for his professional skill and attitude. Those things are an asset that we take for granted all too often. Also, instructed to continue present heading (northeast) to join final, which would ensure a square base turn to final.

Title: DURING A CONFIGN CHANGE AT DAL, A B737 CREW DEPARTED RWY 13R WITH AN INBOUND COMPANY ON APCH TO RWY 31R.
Narrative: THE PROB OCCURRED DURING A RWY CHANGE. IMPROPER OR INCOMPLETE COORD BY THE SUPVRS REGARDING THE STATUS OF DAL DEP/ARR FLOW. ACR XAB DEPARTED DAL (RWY 13R) AND WAS IN IMMEDIATE CONFLICT WITH ANOTHER ACR X JET (CALL SIGN WAS POSSIBLY CD, ARRIVING RWY 31R). AS SOON AS I SAW THE CONFLICT, I CALLED TFC AND TURNED ACR XAB, BUT NOT BEFORE SEPARATION WAS LOST. SUPPLEMENTAL INFO FROM ACN 571788: I WAS THEN ATTENDING TO OTHER TFC WHEN A SUPVR ASKED IF I WAS 'STILL TALKING TO ACR X 737.' I SAW THE PROB, ANOTHER ACR X (ACFT #2) HAD DEPARTED RWY 13R AND WAS RWY HDG PARALLEL TO THE ACR X. I HAD CLRED FOR RWY 31R. I INSTRUCTED ACR X TO TURN R TO 360 DEG HDG AND CANCEL HIS APCH CLRNC. HE ASKED WHY, AND I INFORMED HIM OF HIS COMPANY TFC. HE REPLIED THAT HE HAD HIS COMPANY IN SIGHT. I TOLD HIM TO MAINTAIN VISUAL SEPARATION FROM HIS COMPANY AND CLRED VISUAL APCH TO RWY 31R. HIS COMPANY TURNED SBOUND L TO THE ACR X B737 I WAS TALKING TO AND WAS NO FACTOR. SEPARATION WAS ALWAYS MAINTAINED, BUT THE WHOLE PROC WAS CARELESS, SLIPSHOD, AND BASICALLY STUNK. MANY THINGS WENT WRONG. AS ALWAYS, THE PLT(S) SHOULD BE COMPLIMENTED FOR HIS PROFESSIONAL SKILL AND ATTITUDE. THOSE THINGS ARE AN ASSET THAT WE TAKE FOR GRANTED ALL TOO OFTEN. ALSO, INSTRUCTED TO CONTINUE PRESENT HDG (NE) TO JOIN FINAL, WHICH WOULD ENSURE A SQUARE BASE TURN TO FINAL.
