USE: is for importing a single module, as in `USE: foo`. It's primarily intended as a shorthand for interactive use. In source code you should always write out USING: as in `USING: foo bar ;`. > To continue with this task, I now need to figure out how to process a > directory > of csv files, extract the same bits as above and append them in one big csv > file > like so: > > 24/02/2012,1029,998 > 22/02/2012,1803,1799 > and so on... > > The big directory of csv files was created by running a Windows shell command, > and then a Python OpenOffice-to-csv script from original Excel xls files.

To iterate over the files in a directory, I would recommend looking at the `with-directory-files` function, which will change to a directory then call a quotation with a sequence containing the names of the files in that directory. You should be able to just use `each` to apply your existing code over that sequence. -Joe ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Factor-talk mailing list Factor-talk@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/factor-talk
