I think it's rather common, even nowadays. I'm in computer engineering and not CS, but I've had many exams where I had to write C, C++, Java or Matlab on paper (introductory classes, system programming, OOP...). I've seen this posted before as well. Now, the Pascal bit is probably becoming rarer :)
