comment How to generate characters by a function which works like the Esc + a + ESC
@Mr.Wizard You're welcome to improve it. It's definitely a bit rough around the edges at the moment.

Looks like you might have use FindRoot to get a numerical solution (M2 -> 3.22983).

comment Determine the Number of Lines in a Text File
As written, the code is reading char by char. Who knows if the underlying implementation is reading in more efficient chunks? I agree that C++ I/O is a bit disappointing (and not the easiest to use either!). I might go buy a solid state drive to compensate.

comment Find point at which equation stops having roots (if it exists)
The help tells you how to go from the generalised incomplete gamma function to the incomplete gamma function. Then you could just evaluate the integral directly to get the rest. Or many pages (such as mathworld) give the identity for integer arguments.
