Common Lisp Tutorial - (2) Functions and If. Also lies

In this tutorial I will lie about learning how to define your own functions, and then I will lie once more about the same thing. Afterwards I go over some more data types such as vector, string, and list, while going over the princ function which produces output to a user. Afterwards we learn a little bit about the if special operator as well as truthiness and fakiness via T and nil. I also very briefly discuss some basic data types. Next time I promise we'll go over defun and other macros Uncheck the "Hide Extensions" folder option on Windows: http://windows.microsoft.com/en-US/windows-vista/Show-or-hide-file-name-extensions That's for Vista, it'll work essentially the same on XP or 7, just get to folder options and one of them will be a checkbox for it.
