续前一个帖子“SAS新手竭诚求教代码编写(1)" http://www.pinggu.org/bbs/thread-950347-1-1.html, 另外两个问题还是和macro有关，100论坛币悬赏解决：
Q4. 完成以下macro.

%macroprocessyear(Inputds=StudentScore, Year=91,Outputds=Year_out);

%mend;

Year_out should have the following variables:
Year- Year specified in the input.
StudentHighScore- “StudentID “of the student with thehighest score for that year.
YearAvg- Average for the input year.

Q5. Write a SAS macro to create individual student files foreach student/year combination.
