-
- Yes, you are absolutely right. There is a silly round-off bug in my
- program which I have just corrected for the next version coming out
- in the near future. In fact looking at it I noticed that there was
- another bug in the same procedure. The result was to be given with
- one decimal, but the decimal was always came out zero.

- No, I do not think I'll do that. The purpose of the game is to teach
- the conventions of analytic geometry to the user, not to be easier.

- Then you have an excellent opportunity to try to make her
- understand, since obviously the game gives her the motivation to
- try. If so, my game has served its most important purpose.

-
- The same applies. That would dilute what I wish to teach the user.

-
- Excellent, just excellent! That is exactly what you should do to
- enhance the learning process.
-
- Thank you for the nice and useful feedback. I welcome and appreciate
- it.

-
- That is a nice suggestion, but there are two reasons why I can't
- adopt it. First, I am not familiar enough with the soundex
- algorithm. Second, this is more of a learning aid than a game.
- Spelling right is part of learning a foreign language. English is a
- prime example since words are not pronounced like they are spelled.
- (In Finnish they are.)
-

-
- It is switch for a case-insensitive comparison that also ignores
- hyphens and the potential spacing. This _is_ covered by the
- documentation in TSGMEC.INF :-).

- That is a very generous offer, and much appreciated. However, it is
