Dear Mr. Weiss and Lachenbruch,

I am sorry that I should be more clear when describing my question. In
my opinion, I need to be careful about this problem : for example, for
a variable  that has 10 scales, the 9 value means a real scale and 99
in that case means "not answered".

The pattern is like this:
(1) if the maximum value  of a variable is smaller than 9 , then the
"not answered" takes the value 9;
(2) if the maximum value  of a variable is smaller than 99 but greater
than 10, then the "not answered"   takes the value 99;
(3) if the maximum value  of a variable is smaller than 999 but
greater than 100, then the "not answered"  takes the value 999;
and so on.

(And you are absolutely right for the reminder that there are values
such as 7,8, 98, or 97 to indicate "refused to answer" "invalid
answer". Here I would like to keep focus on one example of "not
answered" , because the other values could be dealt with using the
same way.)

Thanks for help from both of you!

Best regards,
Amanda
