This is a answer from Learning SAS® by Example: A Programmer's Guide, Second Edition. But I think the rusults are not the what expected to get.    Q: Using the permanent SAS data set Survey1, create a new, temporary SAS data set (Survey1) where the values of the variables Ques1–Ques5 are reversed as follows: 1  5; 2  4; 3  3; 4  2; 5  1.   *13-1; data survey1; set learn.survey1; array Ques{5} $ Q1-Q5; do i = 1 to 5; Ques{i} = translate(Ques{i},'54321','12345'); end; drop i; run; title "List of SURVEY1 (rescaled)"; proc print data=learn.survey1; run; proc print data=survey1; run;   List of SURVEY1 (rescaled)  Obs Subj Q1 Q2 Q3 Q4 Q512345 001 1 3 5 4 2 002 5 5 4 4 3 003 2 1 2 1 1 004 3 5 1 4 2 005 3 3 3 3 3 List of SURVEY1 (rescaled)  Obs Subj Q1 Q2 Q3 Q4 Q512345 001 5 3 1 2 4 002 1 1 2 2 3 003 4 5 4 5 5 004 3 1 5 2 4 005 3 3 3 3 3 ...

Hi,    I'm confused with the numerical variable's width and its maximum value?   - The following is from the book: 3 bytes -> 8192, 4 bytes -> 2097152 ... - But in my understanding, the maximum values are: 3 bytes -> 2 ** 24 -1 = 16,777,215, 4 bytes -> 4,294,967,295 ...   So, I don't understand the logic in  SAS's bytes in variable definition?   thanks James ...
