我延伸一下，我们首先确定你的大变量包含的字段数可以被你的设定值整除，例如你有25个，分成4份，最后一个可能被遗漏、或者写的稍微复杂一点

谢谢，我试试扩展下，主要是为了调整输出结果

请教一下，如果不确定个数，如何保证不遗留变量？

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.
