AB543QQQ is "alphanumeric," and it will NOT convert to a numeric (short of a
really large base), so please give an example of what types of conversions
you're expecting to do.
Please don't start a new thread that's simply a duplicate of an existing
thread. Spreading the conversation around is a great way to lose the
interest of all parties involved, and in any case it makes it hard for
those coming along later looking at the discussion in an archive to see
all of the relevant parts of the discussion.
