I've always been somewhat skeptical of TIOBE numbers, but this time I'm utterly confused. VB is listed as "(Visual) Basic" and under the "Very Long Term History" chart it is ranked #4 in 1985. Is this referring to plain old BASIC? Additionally, there's another entry further down for VB.NET at 0.323% -- if it is added to the VB percentage, it would bump it above Python and C#.
