1. I have not tried running your code. But a few observations:
a) Before ever running the script, you might want to consider saving your settings out to file such that you may load them in from your JScript to ensure a consistent environment. This is also the only way that I've found to set your optimization target by the way.
b) No need to wrap Explore call in braces (i.e. don't need {}). Same with block for exporting.
c) Don't think that you need to save your database or restore all after the exploration.
2. AB.ActiveDocument.Name = "RUT-I";
3. Not sure what you're asking here. Do you want to generate 10 .csv files, or read in from 10 .csv files? Assuming that you want to generate files, you can do the preparations/explore/export in a loop.
