My app then needs to read in dynamic data, a set of 4 CSV files, and I had been using Microsofts ODBC driver with HDBC.ODBC and that worked too.
When I try to swap it for Takusen though I get an

Which is a bit of a shame, because using the ODBC text driver was much simpler than parsing the CSV files.

A simple but powerful way to access CSV files is via TxtSushi, which gives SQL access to CSV files, without needing ODBC:

You'd have to use it directly, since afaik it won't work with Takusen, although a Takusen back end for it ought to be possible.
