Narrative:
Crj checked on descending to FL250. I descended him to FL210. For traffic; I stopped him at FL240 and turned to heading 090 degrees. Clear of that traffic; I cleared him on course. Then due to additional traffic at FL240; I turned him back to heading 110 degrees. I turned the B712 right heading 360 degrees and climbed to FL270.
