Narrative:
We were IFR at 13000 ft wnwbound on a vector to J-70. TCASII showed traffic ahead below us and climbing, headed towards us. ATC advised us of VFR traffic ahead 1 mi and climbing -- at the same time, TCASII announced 'traffic, monitor vertical speed.' I took control of the aircraft and started a slight right turn. At that time, the first officer noticed the VFR aircraft, an light transport, climbing about 1/2 mi off to our left and about 600- 800 ft above us. We then resumed our heading and confirmed with departure control that the other aircraft was VFR. No intended evasive action was taken. TCASII was a great help in this situation.

Title: AN ACR MLG RESPONDED TO TCASII RA. THE MLG TURNED IN RESPONSE TO A TCASII COMMAND.
Narrative: WE WERE IFR AT 13000 FT WNWBOUND ON A VECTOR TO J-70. TCASII SHOWED TFC AHEAD BELOW US AND CLBING, HEADED TOWARDS US. ATC ADVISED US OF VFR TFC AHEAD 1 MI AND CLBING -- AT THE SAME TIME, TCASII ANNOUNCED 'TFC, MONITOR VERT SPD.' I TOOK CTL OF THE ACFT AND STARTED A SLIGHT R TURN. AT THAT TIME, THE FO NOTICED THE VFR ACFT, AN LTT, CLBING ABOUT 1/2 MI OFF TO OUR L AND ABOUT 600- 800 FT ABOVE US. WE THEN RESUMED OUR HDG AND CONFIRMED WITH DEP CTL THAT THE OTHER ACFT WAS VFR. NO INTENDED EVASIVE ACTION WAS TAKEN. TCASII WAS A GREAT HELP IN THIS SIT.
