How do I measure single AI data over more than 1 channel

I want to aquire AI data using a Lab PC+ card. Single point AI data from 1 channel is no problem (using AI_Vread) but I want to get data from 2 or 3 channels at the same time. My current program Borland C++ is very basic (my first programming attempt) getting AI data from 1 channel every 20 sec. How can I get the data from other channels as well ?

The AI_* functions are for single-channel, one-shot operations. For your card, you should use the Lab_ISCAN_* functions.
