请教：如何读入多个文件夹下的所有指定文件？

shiyiming

工作中需要将多个目录（总数不确定）内的ABC.TXT读入到一个数据集，请教应如何获取文件所在目录?
  我尝试用以下代码获取文件所在目录，但是x命令必须手工输入EXIT退出。请问，是否有方法可以运行DOS命令且不需要手工干预，或是别的方法实现该目标？

代码：
    x 'd:\test\abc.txt /s >directory.dir';
    data directory;
    infile 'directory.dir';
    input   xxxxxxxxx;
    run;

你可以 environment variable stores all the paths

eg.
set DIR_PATH = D:\test\abc.txt;C:\temp\abc.txt;

Then,
After called up SAS, get back the environment variable DIR_PATH as macro variable

data _null_;
    path=sysget('DIR_PATH');
    call symput('FILE_PATH',path);
run;

Then marco variable &FILE_PATH stores all paths you needed.
You can just use function SCAN() to get every path delimited by ';'

Add the statement below in your pgm.
options noxwait;

该选项可以替代手工输入EXIT退出.
