	)

Reads info line from specified line and stores information.

Exceptions:

Throw Throw Throw

Returns:

Returns TRUE if the CDD file read should continue; otherwise, stop reading in the current CDD.

Reads information line from specified string, stores its information, and creates a new database in the database list.

Parameters:

	line	Pointer to string containing information line to parse
	read_mode	Type of read being performed
