VHDL 1993 defines four types of objects, files,
constants, variables, and signals.
The purposes of the file object are listed above. Files may be
opened in read or write mode. Once a file is opened, its contents may
only be accessed sequentially. A detailed description of the use of
file objects is beyond this module and will be discussed
further in the 'System Level VHDL module'.
