Apart from this hypertext manual, you have a number of special programs
that may allow you to see more clearly what happens in symbolic logic.
All these are stored in the files for the group Symbolic Logic atYahooGroups.com.
To run them (they are DOS programs) you need to be working with a Microsoft
Browser on a PC (not a MAC).
They may be copied to your own computer, or you may run them by clicking
on "run from current location."
