大家也可以尝试下运行看看这个程序，看看会不会出现相同的问题
谢谢啦

我只会用SAs里面的实验设计，编程好难

我刚试了一下，确实会遇到这样的问题，不知道原因是什么

官方解释是反向查询函数的问题:

When you use the FTP, URL, or SOCKET engine in SAS® 9.2 Phase 1 (TS1M0) in a FILENAME statement, you might receive the following error if the remote host's HOSTNAME cannot be resolved to a valid remote host name:

NOTE: UNABLE TO CONNECT TO HOST host name. CHECK VALIDITY OF HOST NAME.ERROR: OPEN FAILED FOR FILE file nameERROR: HOSTNAME host name NOT FOUND.
This error is likely caused by a problem with the reverse lookup function.
Select the Hot Fix tab in this note to access the hot fix for this issue.
An example for using the FTP engine would be the following:

filename lcl ftp 'test.sas7bdat' host='<host_name>' user='<userid>' prompt
         cd='<Path_to_the_folder_where_test.sas7bdat_resides>' recfm=s debug;

FILENAME rmt 'c:\test.sas7bdat' recfm=n;

DATA _NULL_;
   N=1;
   INFILE lcl NBYTE=n;
   INPUT;
   FILE rmt ;
   PUT _INFILE_ @@;
RUN;


建议：重装一个好用的SAS

或者按照官方说法下载一个HOT FIX...

Hot Fix 好用与否 未测试。

这个帖子中 爱萌  说是因为9.2版本的问题，9.1.3就可以
真心不知道为什么高级的版本反而不行...
