INSTALLING XXXPERT

          XXXPERT  should be installed on a diskette along with a copy
          of  your  DOS system.   The easiest way to do this  is:   1:
          Insert  your DOS diskette in drive A.   2:  Insure that A is
          the default drive.   3: Insert a new floppy disk in drive B.
          4: type: format b:/s 5: press return.  6: Insert the XXXPERT
          distribution disk in drive A.   7:  type:  copy a:*.* b:  8:
          press return.

          The new disk will then be ready to use as your expert system
          disk.   Alternatively, XXXPERT may be installed on your hard
          disk.

          DEVELOPING RULES

          XXXPERT   is  a  rule-driven  system.    Rules  are   simply
          statements  of  logic that you wish to have applied  to  the
          area  of  expertise  your  rules  are  to  address.    These
          statements  are  written  in  English  and  ab-  breviations
          thereof.    The first rule statement in a rules file must be
          on  a  line by itself (and on the first line of  the  file).
          This  statement  must specify the name of the goal  for  the
          consultations  to be performed with the set of  accompanying
          rules.    In the CAR rulebase the goal is PROBLEM since  the
          purpose  of  the  CAR  consultation is to  deter-  mine  the
          problem with the car.   The goal in a rule file is always an
          identifier  (a fieldname or variable)  to name the object of
          the   consultation  process.    XXXPERT  will  use  all  the
          subsequent  rule  statements to seek a value for  the  goal.
          Each rule statement after the first must be of the following
          general  form:  IF ==== EQ ---- AND ==== EQ ---THEN ====  EQ
