以交互行模式调用SAS

我在UNIX环境中以交互行模式运行SAS

我使用命令“模块加载SAS/9.4”；“sas-nodms”
然而，它表明：

You are running SAS 9. Some SAS 8 files will be automatically converted 
by the V9 engine; others are incompatible.  Please see 
http://support.sas.com/rnd/migration/planning/platform/64bit.html

PROC MIGRATE will preserve current SAS file attributes and is 
recommended for converting all your SAS libraries from any 
SAS 8 release to SAS 9.  For details and examples, please see

This message is contained in the SAS news file, and is presented upon
initialization.  Edit the file "news" in the "misc/base" directory to
display site-specific news and information in the program log.
The command line option "-nonews" will prevent this display.

我不明白数字1？2是什么意思。

非常确定这些只是日志号，错误本身告诉您如何抑制该输出：

命令行选项-nonews

---

您基本上是使用该命令启动SAS，而不是实际调用您的程序。SAS启动时，这是将出现在日志中的代码

这些数字提示您输入SAS代码。必须输入三个空行才能显示1到4

---

完成后，您可以使用endsas；命令退出SAS。

非常确定这些只是日志号。
