PC-Hypertext: Attributes 4.

- The PC-Hypertext System includes nominal security features to
ensure the integrity of the system's data and as an aid to
application developers and users.  These functions corroborate
the existence of idea nodes and create the network paths that
link the associated ideas.  These security functions primarily
serve to protect the integrity of the hypertext application by
informing application users of the status of system files.  When
the PC-Hypertext application is implemented, this rudimentary
security system validates the requisite information files and the
system structure as a guard against accidental or unintended
corruption of the information base by negligent or uninformed
users.
