This interface can be used to read/write certain properties of the active DSS object. The structure of the interface is as follows:

int32_t IsourcesI(int32_t Parameter, int32_t Argument);

This interface returns an integer number with the result of the query according to the value of the variable Parameter, which can be one of the following:

Parameter 0: Isources.Count

This parameter returns the number of Isource objects currently defined in the active circuit.

Parameter 1: Isources.First

This parameter sets the first ISource to be active; returns 0 if none.

Parameter 2: Isources.Next

This parameter sets the next ISource to be active; returns 0 if none.
