JingJu11: My classmate provided the following code
Some people raised a question to my friend: Any pros and cons on programming on pure macro syntax vs. using some other interfaces, such as data step or procedures? The answer is: if you can program on pure macro syntax, you should do it. Because you can place the code anywhere you want; on the other hand, doing macro programming on data step or procedures can only work wherever it is suitable. It usually works as an independent function-like unit. The bad thing for macro syntax programming is that always is hindered and complicated by macro variable masking scheme.
