HOW DOES THE FILEMAKER PRO INDEX CONTROL THE PLAYBACK OF A VIDEODISC PLAYER FROM A MACINTOSH COMPUTER?
In order to control the videodisc player, we are using a combination of functions integrated into Operating System 7.x or 8.X and FileMaker Pro 2.x (or greater). The actual operating commands are sent to the videodisc player through a HyperCard stack called SLICE DISC DRIVERS. It uses the Voyager Company’s Videodisc Drivers (under license). These communications are looped back to the FileMaker Pro database through the functionality of “Apple Events.” Apple Events is a System 7.x or greater technology that lets applications communicate with one another on the same Macintosh computer or over a network. It is primarily a data transport mechanism. Both the sending and receiving applications (FileMaker Pro and SLICE DISC DRIVERS) must agree to use a mutually understood data format. Version 2.x (or greater) of FileMaker Pro and the version of HyperCard we are using for SLICE DISC DRIVERS are both Apple Events aware. SLICE DISC DRIVERS is designed to run in the background if you use the FileM
