ASCII:Specifications
The ASCII driver reads and writes standard ASCII files without field delimiters. This is often used for mainframe data import/export with an ASCII flat-file. By default, a carriage-return/line-feed delimits records. The ASCII driver does not support keys.

Due to its lack of relational features and security (anyone can view and change an ASCII file using Notepad), it's unlikely you'll use the ASCII driver to store large data files. But it can help you create a text file viewer–use it to open a file, and read it in to a multi-line edit or list box control.
