Um man I don't mean to be a douche but I've never heard of filemaker 9 and if your just starting vb in my book your still a novice (no offense .) personally I would recommend any C derived language and or python and if your going to be doing extensive work on txt based files I would insist on perl. C is a good choice its powerful and it's big brother c++ has an ungodly amount of libraries . Everybody will tell you to start with vb because it's supposed to make learning c and other languages easier but if you drop vb cold turkey and go directly to c it'll go fast man
C & C++ are widely used so information is plentiful.
