IT'S OFTEN DIFFICULT TO DEscribe in words how a brand new computer program operates. But realistic demonstration versions can also be costly to build because of the complex programming involved. Now, help is on the way from the Lifeboat Publishing arm of Voyager Software Corp. in Shrewsbury, N.J., which has come out with Dan Bricklin's demo-it!--created by the pioneering programmer behind VisiCalc, the original spreadsheet program.
demo-it! helps build lifelike simulations of any Microsoft Windows-compatible program. It can incorporate screen images directly from the original software as well as working menus and buttons that a viewer can activate with a mouse and keyboard. What's more, animated text and graphics and digitized sounds can be added as annotations. The resulting demo programs are usually small enough to fit on a single floppy disk or even be sent over the Internet. demo-it! lists for $399 a copy, but there's an introductory price of $199.
