幸运的是SAS引入了一系列Q开头的macro function,在本例中使用%QSYSFUNC代替%SYSFUNC: %let label = %qsysfunc(attrc(&dsid, label)); 可以屏蔽ATTRC函数获取的label中包含的&或者%,从而达到我们最初设计macro的目的。 从这个例子里面我们还可以看到%QSYSFUNC屏蔽的特殊字符与%NRBQUOTE相当,即各类特殊字符(包括&...
I have got some problems to call macro functions within macro functions. For instance, why does that little program returns the following error : ERROR: A character operand was found in the %EVAL function where a numeric operand is required. The condition was: 20+ 50; %macro one(A...

自动生成宏变量有两种方法,data步里用call symputx(),或者proc sql中用select into:。 零售项目中,万同学的代码里有很多select into:的使用;唐同学的宏里面就有不少call symput()。 call symputx的用法举例: /*6.1b using symputx to create a macro variable*/ /*生成宏变量jane_age,取值为Data步生成的数据...
