TEXTIO defines two new data types to assist in text handling.  The
first is the LINE data type.  The LINE type is a text buffer used to
interface VHDL I/O and the referenced file.  Only the LINE type may
read from or written to a file.
The second is the FILE type of TEXT.  A file of type TEXT may only
contain ASCII characters.
Several of the procedures provided by TEXTIO for handling text
input/output are also listed in this slide.
