Thanks for the help. I have since made about 30 techs using the program you made.

No problem, glad you are getting good use out of it.
Now, for your other questions:
a) Crime is not implemented. I've heard tell that originally your bank account would take a "corruption" hit every now and then (or monthly, I'm not sure), and this bonus would presumably lessen the hit. You can ignore it for now.

Cabinet is not implemented. I've never heard what it was supposed to do in the first place.
c) Government supposedly is implemented. It affects how easy it is to win elections. I haven't tested this though. Ever since 1.1 I've never lost an election, Morale is too easy now.
d) Yes, Interest Rates are counter-intuitive. Bonuses are positive, and reduce the amount of months on a lease, so a +10% bonus would reduce a 100 month lease to 90 months. It does not appear to effect the down payment or monthly BC amount, just the number of months you pay.
If you enjoy using my program, you should know that I just released a new version that adds a bunch of features. You can download it at the website.
