In a DATA step view in Version 8, using certain Boolean numeric
expressions, can cause incorrect results.  The problem appears when
the results of a Boolean comparison are assigned to a variable, and
the next run time statement is a Boolean comparison.  The following
code demonstrates the problem.

  DATA VW/VIEW=VW;
    X = 6;
    Y = X > 5;
    IF Z THEN W=10;
    *IF Z > 0 THEN W=10;
    PUT W= X= Y= Z=;
  RUN;
  DATA _NULL_;
    SET VW;
  RUN;

Using the two different forms of the "IF Z..." condition generate
different results.

To circumvent the problem, use the second form of the "IF Z..." test,
i.e. the one that is commented out in the above code.
