ReplyDeleteDear SaS exam preparer;
ReplyDeletePlease do not confuse us, did you try if it works ? Then give us the detail info so we would be clear in out mind what exactly it works and why it works. If we confuse here then we are our own at the exam.
You understand me right. Do not pass confusing statements, put it sas program and copy the program and your output too.
thanks

Learning how to take exams is as important as the information in them. As you look at all the possible answers - from the place where we are at this point, "keep" and "copy" have not been introduced. And do not really make sense to go extra steps for such a basic function as taking a temp dataset and making it perm. So if I did not know exactly, I could deduce that the code that represents what we have most recently covered would be my best guess - and knowing the function of making a temp dataset perm is very common and/or necessary, using this kind of logic will help deduce from mult choice which answer is correct.
Deleteit is A. copy is used to transfer one file to another liabrary.

ReplyDeleteI didn't find copy as a valid SAS statement
ReplyDeleteCOPY statement exists in SAS.
ReplyDeleteHowever, it cannot be used inside a Data step so A is not a correct answer. D is the correct one.

COPY statement cannot be used in datastep. It is used in a proc step as follow:
ReplyDeleteproc copy in=work out=sasuser;
select datasetname;
run;
