TextRec describes a text file. This record is made available so it can be used to implement drivers for other than the normal file system file records.
To implement a driver, an Assign procedure must be implemented, which fills in the various fields of the record. Most notably, the callback functions must be filled in appropriately. After this, the normal file operations will handle all necessary calls to the various callbacks.
