//  Library Call Demonstrated:    Mccdaq.MccBoard.AInScan()in Foreground mode
//                                with scan options = MccDaq.ScanOptions.ConvertData
//
//  Purpose:                      Scans a range of A/D Input Channels and stores
//                                the sample data in an array.
//
//  Demonstration:                Displays the analog input on up to eight channels.
//
//  Other Library Calls:          MccDaq.MccService.ErrHandling()
//                                MccDaq.MccService.WinBufAlloc
//                                MccDaq.MccService.WinBufToArray()
//                                MccDaq.MccService.WinBufFree()
//
//  Special Requirements:         Board 0 must have an A/D converter.
//                                Analog signals on up to eight input channels.
