OK. I have just put the code up on my Sequence Generator Code blog (version 2). Refer to recent wiki activity to find it.

The Alpha function can be called from within Excel using =Alpha(r,"","a")

You can also call the Alpha_0 and Alpha_1 rule functions using =Alpha(r,"0","a") and =Alpha(r,"1","a")

There is also the much simpler example function =Simple(r,"p") and =Simple(A7,"q")

The simple function will be easier to follow if you want to undertsand the syntax of Sequence Generator Code.

Cheers
