If your submission is accepted, the abstract is considered final and will be edited so trademarks will be properly acknowledged when your abstract is published in conference materials. The 175-word abstract should include the SAS software mentioned in your presentation, any operating systems your paper is limited to and the skill level of the intended audience.
The working draft is not considered your final paper and will not be published. It should contain at least 1,000 words of actual text and should present the reader with a clear concept of your paper's focus, direction, and quality.
