11, The following SAS code is submitted:
data WORK.TEMP WORK.ERRORS/view=WORK.TEMP;
infile RAWDDATA;
input Xa Xb Xc;
if Xa=. then output WORK.ERRORS;
else output WORK.TEMP;
run;

which of the following is true of the WORK.ERRORS data set?

A The data set is created when the DATA step is submitted
B The data set is created when the view TEMP is used in another SAS step
C The data set is not created because the DATA statement contains a syntax
error.
D The descriptor portion of WORK.ERRORS is created when the DATA step is
submitted

我自己建了一个external file然后试了一下，发现可以成功的compile啊，log也没说有错误，请问为什么答案说选C呢

关键词：Data view VIE Data step following following because another created

记不太清了，好像是“WORK.ERRORS/view=WORK.TEMP;”有问题

如果说有错误的话，那就是RAWDDATA没加引号。

所以这道题是应该选C的？

应该选B吧，只有TEMP被使用的时候才执行这段data step。

没看懂原因，为什么选B。

谢谢。

The VIEW= option tells SAS to compile, but not to execute, the source program and to store the compiled code in the DATA step view that is named in the option.

Note:If you specify additional data files in the DATA statement, SAS creates these data files when the view is processed in a subsequent DATA or PROC step. Therefore, you need to reference the data view before you attempt to reference the data files in later steps.
