The computer is asking you for input to give it the data it needs to
determine which of the possible answers is most appropriate.  You will be
presented with a phrase followed by a numbered list of possible completions
of the phrase.  Select the item(s) from the list that are appropriate for
your problem and input the numbers.  If more than one item is appropriate,
separate the numbers with a comma or space.

If you do not understand why the computer is asking you this question, you
can ask it what rule it is trying to apply by typing "WHY" and then pressing
the <ENTER> key.  The computer will respond by displaying the rule it is
trying to determine the validity of.  You will notice that the qualifier it
was asking you for is in the rule's IF part.  Press <ENTER> and the
computer will either re-ask you the original question or display another
rule.  If another rule is displayed, it is because the first rule shown was
only being used to derive information for another rule.  The computer will
continue displaying rules until it reaches the base rule it is trying to
apply.  This rule will have one or more choices (the possible solutions to
the problem).

If you would like more details on the meaning of the question being asked,
press <?> in answer to the question.  The author of the knowledge base
may have created a file of information on the various questions.  If 
such a file has been created, additional information will be displayed.
If there is no such file, the program will tell you.

If you want to store the data you have input so far and exit the program
enter QUIT in response to the request for information.  The program will
ask you the name of the file you want to store the data in.  DO NOT use
the name of the knowledge base, if there is already a file with the name
you select, it will be erased.
