-- part name: Dukakis Vaccine Script
----- HyperTalk script -----
-- Note: "Duk-akis" contains a dash here to prevent the vaccine from
-- detecting itself as a virus.

-- Script to detect the spread of the “Duk-akis” virus. It works by
-- trapping the “set” command. I haven’t seen “Duk-akis”, but I should
-- think that it works by setting the scripts of various objects to
-- whatever they were plus an “on openStack” handler. Well, by trapping
-- the “set” command, we can then find out if we are setting a script.
-- If we are, then we can sort of work like “Vaccine” does; i.e., we
-- prompt the user to see if he or she wants to allow the command to
-- continue. If it is stopped, then all scripts are halted.

-- Additionally, if the script contains the word “Duk-akis”, then no
-- option is given — the script is halted straight away.

-- THIS SCRIPT SHOULD BE INSTALLED IN THE “HOME” STACK,
-- IN THE STACK SCRIPT.

-- You can test this script by making a new stack, then keying the
-- following examples into the message box:
-- • “Set the script of this stack to empty”
-- • “Set the script of this stack to field 1”
-- • “set the script of this stack to Duk-akis” (don’t type the dash)

-- Try it, I think you’ll like it!

-- This script is free to everyone apart from the person who wrote the
-- “Duk-akis” virus. I just hope it affects every single stack he or
-- she has or gets in the future!

-- Modified slightly 8/22/88 by Joe McMahon to make sure that
--"set the script…" (vs. "set script") doesn't slip through.

-- Modified a bit more 8/29/88 by Joe McMahon to add Ian's fixes
-- to prevent the vaccine from detecting itself as a virus.

   The Dukakis Vaccine was written by Ian Summerfield.  It is a HyperCard script designed to both detect the Dukakis virus and to prevent its invasion into stacks. The script is general enough to be of utility in blocking other HyperCard-only viruses.
   Dukakis Vaccine only monitors changes to scripts; it cannot block viral XCMDs or XFCNs. It does not remove the virus, but blocks it and alerts you to the virus's presence.
