This update incorporates keyword encryption into the password system.  It
requires the user to have not only a password but a security code which
is not recorded but used as a keyword to encrypt the password.  It doesn't
matter if the password and security code are the same.  Currently there is
one user in the database: USERNAME: SYSOP
                          SECURITY CODE: SYSOP
                          PASSWORD: SYSOP

The only files you need to replace are the ones that I have included.  (The
ADDCODE.PRG file contains 3 lines which you must add to your existing setup/
cleanup code)
