apologies, error is   “;” is not a valid filename, rather than “.” is not a valid filename

I don’t have that book but I would check that you haven’t tried to copy/paste from the book itself. Whilst it is generally readable by the human eye the code would not format correctly within the IDE. Try getting the code directly from the download links given in the book.

Hi Arthur.
Did you proceed as Steve mentioned?
Don’t copy the code directly from the eBook. Copy it from the link available next to the code section.
Regards,
Sara

Yes, thanks for the advice Steve, despite my careful checks after copy and paste I had missed a couple of bits of unwanted text, all sorted now.
