Simple Dialog based example demonstrating a polled mode
read from analog input channel 0.

Tested with DAS-16 in Win98SE with DriverLINX from SF-037A01
CD (final release) and Visual C++ 6.0 Standard Edition.

Will work with any board which has a DriverLINX driver and
an analog input channel 0.

Unlike many boards, the DAS-16 does not have programmable gain.
Instead the gain of the analog input is set by switches on the board.

This example was written with assumptions of -10 to +10 volt range is used.
If your board is at other ranges, the code will require adjustment.

boards with gain controlled by switches:  DAS-16 and DAS-16F
board with gain controlled by software:  DAS-16G1 and DAS-16G2
