I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in the classical Greek synthetic form and in the more modern analytical form.

@eldo. I see no contradiction in my behavior. I answer the question because I want to help the OP. But neither my answer nor BobHanlon's are likely to help anyone other than the OP, so I nominate the question for closure as too localized. When the question is deleted, I'll loose the pennies, which bothers me not at all.

I recommend you write up your solution as an answer. I think it's quite clean, and, I for one, will up-vote it.

@BobHanlon. I used the OP's modified version of TruthTable, which although clunky, takes care of the problem you mention. I've added that version of TruthTable to my answer to make it self-contained.

This question appears to be off-topic because it is too localized; i.e, it applies only to the local situation and needs of its poster and answers will not benefit others.

Please properly format the code you added in your edit. Dumping unformatted code into a question will diminish your chances of getting an answer.
