  Operation of an accelerator requires the efficient and reproducible execution of many different types of procedures. Some procedures, like beam acceleration, magnet quench recovery, and species switching can be quite complex. To improve accelerator reliability and efficiency, automated execution of procedures is required. Creation of a single robust sequencing application permits the streamlining of this process and offers many benefits in sequence creation, editing, and control. In this paper, we present key features of a sequencer application commissioned at the Collider-Accelerator Department of Brookhaven National Laboratory during the 2007 run. Included is a categorization of the different types of sequences in use, a discussion of the features considered desirable in a good sequencer, and a description of the tools created to aid in sequence construction and diagnosis. Finally, highlights from our operational experience are presented, with emphasis on Operations control of the sequencer, and the alignment of sequence construction with existing operational paradigms.
