The BASIC file driver reads and writes comma-delimited ASCII files. By default, quotes ( “ ” ) surround strings, commas delimit fields, and a carriage-return/line-feed delimits records. The original BASIC programming language defined this file format. The Basic driver does not support keys or backward file processing (thus Basic files are not a good choice for random access processing).
The Basic file format provides a good choice for a common file format for sharing data with spreadsheet programs. A common file extension used for these files is *.CSV, which stands for “comma separated values.”
