The computer is asking 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 items from the list that are appropriate for your
problem and input the numbers.  If more than one item is appropriate
separate the numbers you input with a comma or space.

Since you are changing input and not applying a rule at this point you can
not ask WHY.

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. The QUIT option applies only to the
runtime program and not the editor.
