Point.GetNext (method)

Syntax Point.GetNext
Description To wait for and get the next value of the point. This method returns when a point update is received for the point, based on a previously submitted OnChange , OnAlarm , OnTimed or OnAlarmAck call. If the point never changes, the call never returns. To wait with a timeout, see the GetNext (function.)
Example 
' Calculate the average of the next two point values.
Sub main()
   Dim MyPoint as new Point
   MyPoint.Id = "TANK_TEMPERATURE"   ' Set the Id
   MyPoint.OnChange                 ' Request point onchange
   MyPoint.GetNext                  ' Retrieve the first value.
   x = MyPoint.Value                ' Record the value.
   MyPoint.GetNext                  ' Wait for the next value.
   x1 = MyPoint.Value               ' Record the value
   ave# = (x + x1 )/ 2              ' Calculate the average
   MsgBox "The average was " & str$(ave)
end sub
