如何编写MACRO将规范名称文本导入

shiyiming

Data sets ‘data1.txt’ through ‘data5.txt’ contain variables x and y.  Use a macro do loop to infile all five data sets into SAS。求各位高手写个代码，急

filename f2load ('text1.txt','text2.txt','text3.txt');
data _null_;
    infile f2load;
    input x y;
run;

Alternatively, the infile option filevar= can be used with a do loop. It is not necessary to use MACRO in your case.
