【问题描述】:
我从 SAS 网站获取了一个 SAS 宏,以便列出文件夹中的所有文件。 这是完整的参考:http://support.sas.com/kb/25/074.html。
这就是代码:
%macro drive(dir,ext);
%let filrf=mydir;
/* Assigns the fileref of mydir to the directory and opens the directory */
%let rc=%sysfunc(filename(filrf,&dir));
%let did=%sysfunc(dopen(&filrf));
/* Returns the number of members in the directory */
%let memcnt=%sysfunc(dnum(&did));
/* Loops through entire directory */
%do i = 1 %to &memcnt;
/* Returns the extension from each file */
%let name=%qscan(%qsysfunc(dread(&did,&i)),-1,.);
/* Checks to see if file contains an extension */
%if %qupcase(%qsysfunc(dread(&did,&i))) ne %qupcase(&name) %then %do;
/* Checks to see if the extension matches the parameter value */
/* If condition is true prints the full name to the log */
%if (%superq(ext) ne and %qupcase(&name) = %qupcase(&ext)) or
(%superq(ext) = and %superq(name) ne) %then %do;
%put %qsysfunc(dread(&did,&i));
%end;
%end;
%end;
/* Closes the directory */
%let rc=%sysfunc(dclose(&did));
%mend drive;
/* First parameter is the directory of where your files are stored. */
/* Second parameter is the extension you are looking for. */
/* Leave 2nd paramater blank if you want a list of all the files. */
%drive(c:\,sas)
这个宏(显然)工作正常,问题是在日志中返回结果。 我需要将这些结果放入 SAS 数据集中以安排其他操作。 我该怎么做?
提前致谢。
