Narrative:
We were on V2 (hnl R-110) climbing to 13000 ft. After contacting center; he instructed us to fly a 095 degree heading for traffic and told us to climb to FL230. After a short while; center cleared us to the koa VOR. We were climbing through 14000 ft and proceeding direct to the koa VOR when center instructed us to maintain 13000 ft at which point I noticed we were already climbing through 14400 ft and my first officer questioned center by saying; 'we're climbing through 14400 ft and you want us to descend to 13000 ft?' I noticed on the readout that we had +4 or 400 ft vertical separation and felt that if we descended we would be in the conflicting traffic's path. The TCAS then instructed us not to descend and we got a visual on the B717 at our 11 O'clock low position. He passed directly under us at approximately 500 ft.

Title: B737-200 FLT CREW HAS A TCAS ALERT WHILE CLIMBING TO ALT.
Narrative: WE WERE ON V2 (HNL R-110) CLBING TO 13000 FT. AFTER CONTACTING CTR; HE INSTRUCTED US TO FLY A 095 DEG HDG FOR TFC AND TOLD US TO CLB TO FL230. AFTER A SHORT WHILE; CTR CLRED US TO THE KOA VOR. WE WERE CLBING THROUGH 14000 FT AND PROCEEDING DIRECT TO THE KOA VOR WHEN CTR INSTRUCTED US TO MAINTAIN 13000 FT AT WHICH POINT I NOTICED WE WERE ALREADY CLBING THROUGH 14400 FT AND MY FO QUESTIONED CTR BY SAYING; 'WE'RE CLBING THROUGH 14400 FT AND YOU WANT US TO DSND TO 13000 FT?' I NOTICED ON THE READOUT THAT WE HAD +4 OR 400 FT VERT SEPARATION AND FELT THAT IF WE DSNDED WE WOULD BE IN THE CONFLICTING TFC'S PATH. THE TCAS THEN INSTRUCTED US NOT TO DSND AND WE GOT A VISUAL ON THE B717 AT OUR 11 O'CLOCK LOW POS. HE PASSED DIRECTLY UNDER US AT APPROX 500 FT.
