Narrative:

During cruise at FL330, on a direct route to detroit in the vicinity of indianapolis, ZID called and cleared us for an 'immediate right turn' to heading 100 degrees (not sure of exact heading possibly 090 degrees). Center also requested if possible climb FL350. We said we could accept FL350. We were cleared to FL350. At FL350 center cleared us back on course direct to detroit and thanked us for our help. No other comments were made. The rest of the flight was uneventful.
