logicg11.zip    Problems In Logic (Shareware Version)

Problems In Logic is a program designed to exercise the problem solving 
abilities of students in grades 5 and up.  In order to successfully complete
these problems, the student must use analytic and fact comparison skills.
They are challenged to solve a puzzle using only a few clues provided.  In
order to arrive at the correct answer, they must constantly cross reference
the clues and compare them with data they gather as they proceed.  The program
gives them five chances to solve the puzzle before giving the correct answer. 
The top ten scores (points are awarded based on how many attempts it takes for
a student to complete a puzzle) are saved in a "Hall of Fame" and each 
student's progress is tracked so they can do some problems one day and come
back another to pick up where they left off.

This program may be run from diskette or copied to a hard disk. 

This program is a demonstration version of the registered programs Problems
In Logic Volumes 1 & 2.  It works exactly like the full versions with the
exception that it only has 4 example problems (2 from Volume 1 and 2 from
Volume 2.)

You start the program by entering LOGICG11 at the DOS prompt.  The first
step in using the program is to enter your name.  The program keeps track of
every name, which problems have been completed by that person, and their
total score to date.  This way a student need not complete all of the
problems in one sitting.  They can do some one day and come back another to
pick up where they left off.  Note: when a name is entered, the program scans
for it. If a match is found, you will be asked to confirm that this is the 
right name.  If a new student enters a name which is already in the list,
they will have to choose another, more distinctive, name.  For example, if
there are two students named Mike, Mike Doe and Mike Stevens, they could not 
both enter Mike as their name. One might enter MikeD and the other MikeS.

After a name has been entered the program looks to see which problems have
been completed and then loads the next problem for the student to complete. A
student new to the program begins at problem #1.

The problem screen has a brief description of the puzzle to solve and lists
the clues necessary to solve it.  The bottom portion of the screen is the
chart used to enter clue data and, eventually, solve the puzzle.  Example 
(problem #1 - In the program, each section of the chart is a different color):
==============================================================================
Five couples went to the multiplex to watch movies. Each couple saw a
different movie.  Use the clues to determine who the couples were and which
movie each couple saw.

1. June likes comedies but Tim does not.
2. Marcia didn't go with Scott or Tim and didn't see the love story Susan saw.
3. Gladys and Dave have been going together for a long time.
4. Sandy and Gladys only watch sci-fi or actions films, Tim never does.
5. Dave watched an action film this time and Scott tagged along with Sandy.
6. Henry ended up laughing until his ribs hurt.

The student enters an X in a place on the chart where the clues given could
not exist, and an O where the facts confirm that place.  The cursor keys
control where the highlighted entry cell is.  Pressing the X key places an X,
pressing the O key places and O, and pressing the spacebar clears the cell.
Enter submits the problem to determine if it is right or not (a student has 5 
attempts to solve each problem before the answer is given.)  ESC will leave
the problem and return to the sign in screen.  Note: Students do not get credit
for incomplete problems.  If they leave a problem in the middle, they will have
to start that problem over when they sign in the next time.

In the example, clue 1 tells us that June watched a comedy and obviously did
not go with Tim so we can place an X under all movies except Comedy (where we
put an O) across from June.  We can also put an X under Tim across from  
Comedy and since he did not go with June, we can put an X under Tim across from 
June.  Also, since we know June saw the Comedy, none of the other women 
could have so we can X out Comedy for all other women.  Now our screen looks
like (Note: only the chart portion is shown here):

Clue 2 tells us Marcia didn't go with Scott or Tim (X both of them out across
from Marcia) and she didn't see the Love story (X it out across from Marcia)
but Susan did see it (put an O across from Susan under Love and an X under all
other movies across from Susan, also X out Love for all the other women.)

Clue #3 is a given; Gladys and Dave went together (put an O across from Gladys
under Dave and an X under all other men. X out all other women under Dave. And,
since we know Gladys didn't watch the Comedy or Love story, Dave didn't either.

==============================================================================
Clue #4 tells us that the SF and Action films were seen by Sandy and Gladys so
we can X out any other movie type across from them. Once we do, notice that the
only person left to have seen the Drama is Marcia; put an O there and an X for
the other movie types across from Marcia.  Also, #4 says Tim doesn't watch
those types, so he didn't go with either Sandy or Gladys, which only leaves
Susan. We can X out SF and Action under Tim, and put an O under Tim across from
Susan and X out all other men across from Susan. Since we already know Susan 
saw the Love story, so did Tim; put an O under Tim across from Love and X out
all other movies under Tim. Also we can now X out Love for all the other men.

Continue using the clues (you might have to go back and forth among them as
you gather more data - using a clue once is not always good enough) to fill in

==============================================================================
Press ENTER and the program will look at your answer and check if it is right.
If it is, you will be given a congratulations message and awarded points (based
on how many tries you had to make.) If the answer is wrong, you will be given
a message to that effect and left at the puzzle screen to check your answer.
After the fourth incorrect attempt, the "Number of tries" message will begin to
flash, telling you that there is only one try left.  After the fifth incorrect 
try the answer is displayed and you get no points.

If you have not completed all of the problems, you will be asked if you want
to do another.  If you have completed all of the problems, your total score
will be compared to the top ten list and if your score is higher than one or
more on that list, your name will be entered in the "Hall of Fame" for others 
to try to beat.

The correct answers are:

#1  Sandy ---- Scott ---- SF            #2  Johnson --- Tuna ---- Minnow
    Susan ---- Tim ------ Love              Smith ----- Bass ---- Fly
    Gladys --- Dave ----- Action            Jones ----- Trout --- Lure
    June ----- Henry ---- Comedy            Davis ----- Perch --- Worm
    Marcia --- Fred ----- Drama             Hanks ----- Catfish - Cheese
