Title: What is a Programming Language?

Instructions:  Visit the Data Factory web page.

• Try downloading and running the Even-Odd sorter factory and then the Fibonacci sequence generator. If you run into any problems, check the class mailing list, and if your question hasn't already been answered there, ask it there.
• Next create your own Data Factory program that does the following: generates a stream of random numbers in the range 0 to 9, and then sorts the numbers onto three conveyors depending on their values MOD 3. Thus all the numbers that are congruent to 0 MOD 3 should go on one conveyor, those congruent to 1 on a second conveyor and those congruent to 2 on a third conveyor.
• Save your solution using the File menu's Save As option. Then create a screen snapshot of your factory layout, with the sorted data showing. You can do this by first using the MS-Windows operation Capture the Screen Onto the Clipboard. Then open up Microsoft Paint and Paste the clipboard contents into a Paint canvas. You can select the desired part of the picture using the Selection tool. Then copy to the clipboard, begin a new image and paste the clipboard contents into that new image. Save your .BMP file in case you need it again. Then print the screenshot, put your name on it, and turn that in on Thursday morning with the rest of this assignment.
• Answer the following questions and turn these in with the rest of the assignment. (1) What facilities does the Data Factory offer for specifying "arithmetic expressions?" (2) Is there any kind of storage or variable in the Data Factory? If so, where? (3) In what ways is creating a data factory layout like computer programming? (4) Is the Data Factory's way of expressing computations a programming language? Why or why not?
