in reply to Accessing cells in CSV files
Consider using Text::CSV_XS (or the slower cousin Text::CSV). If that interface is too complicated, consider DBD::CSV (a DBI interface) or Spreadsheet::Read (which needs Text::CSV_XS).
BTW 1100 x 60 isn't really large. Normal computers can read that without problem (unless each field is 600Mb).
Your data-example doesn't show CSV btw, but tab or space separated data.
Enjoy, Have FUN! H.Merijn
