Abstract: SECUR is a DIBOL subroutine callable from any DIBOL program.
It was developed to provide an extra level of security in
certain of our highly sensitive applications.  The subroutine
makes extensive use of DIBOL's internally callable features
to make it virtually impossible for anyone to discover the
name of the password file or module name.  Provisions have
been made to allow the entry and updating of passwords, using
oldpassword frontslash newpassword.  An optional feature is
the ability to save all unsuccessful attempts, with the date,
time, password used and terminal line number.
 
It is assumed the user is sophisticated enough to establish
the required disc files using KED, and can compile the source
module and modify any application program needing additional
security.
 
The subroutine is extremely well documented within the source
code module and can be modified by the end user to meet any
changing need.
 
Restrictions: Must be called as a subroutine.
