Abstract: This sampler demonstrates a document with several embedded computations. For example, one part of the document is a time-of-day reminder. Another example is a database query from a telephone whitepages database. A third example incorporates the result of executing a command file within the Cedar environment. A final example is an animated sequence of a potential surface. XEROX Xerox Corporation Palo Alto Research Center 3333 Coyote Hill Road Palo Alto, California 94304 For Internal Xerox Use Only 1. Time of day reminder Every time this paragraph becomes visible on the display, it updates the current time of day:
current time 2. Telephone whitepages database query The following telephone enteries come from the whitepages database of Doug Terry. They appear in this document as the result of executing a database query: find all entries with names that begin with `T' ///Users/Terry.pa/Whitepages/TerryTDir.lbdf name(wildcard): terry* ///Users/Terry.pa/Whitepages/TerryTDir.lbdf name(wildcard): terry* 3. Execute a Cedar command file The following material is not persistent with the document. It was generated by executing a series of commands at the workstation. Today's date: date date Current Cedar version: version version Workstation name and net address: hostname hostname 4. Animation of light on a potential surface This animation demonstrates the connection between a document and computation. A small animated movie of light reflecting from a potential surface provides insight into the structure of this surface.
