Hi Steven,

Well, it's quite old (and not supported by Bentley anymore) version, but still good enough ;-)
In my opinion it's better to use MicroStation VBA, its implementation in V8 2004 Edition is good and stable.

Do you have Excel installed? In general I don't like to use other software and libraries, because it creates extra dependencies and increases a threat something will not work correctly on another computer, but it seems to be good solution in your situation. Excel is able to read CVS files and MicroStation VBA can reference Excel and to use it's functions (and vice versa).
With regards,
Jan
