I had trouble with this because the only definitions I could find involved things like Subscript[(q;q), Infinity] and I had no idea what that was. I have since learned that this is called a q-series as defined at http://mathworld.wolfram.com/q-Series.html I often look (out of curiosity) at the definition of special functions in Mathematica. In almost every case I can see that a function is the solution to a certain differential equation, a definite integral, or something else I am familiar with. Even the very general AppellF1 function is defined as a double infinite series, and I know what that is. ----------- Ted Ersek
