I don't actually believe I'm getting involved in this discussion, since, again, this is my oppinion and based on what I personally have used over the years. I agree with someones previous comment on basic. It's quite non-standard and trying to work out what commands are available, and how in your version of basic is enough to give you a headache. At least that's certainly what I found. My advice is either perl or python. I currently like python more than perl, but unless your screen reader can tell you how much each line is indented by, it could be a bit of a pain. The only difference from other comments here is that if you find sigwin speech unfriendly, there are native windows implementations of perl and python. I've never used them, but I know that active state for one has a windows version of both.
