Foregroound and background?

AInScBg.VI - Background analog input scan
Repeatedly scans a range of analog input (A/D) channels in the background. The channel range, the number of
samples, the sampling rate, and the A/D range can all be specified. The collected data is stored in an array.
AInScFg.VI - Foreground analog input scan
Repeatedly scans a range of analog input (A/D) channels in the foreground. The channel range, the number of
samples, the sampling rate, and the A/D range can all be specified. The data that is collected is stored in an array.

Well maybe you do but did not realize it.

Kidding aside, I agree with Dennis that you should go through MC to get those Q's answered properly.
