Clinical Trials Programmer certification preparation

[ttp]

The following question will ask you to provide a line of missing code.
The following program is submitted to output observations from data set ONE that have more than
one record per patient

proc sort data=one out=two;
by subjid;
run;
data two;
set two;
<insert code here>
if (first.subjid ne 1 or last.subjid ne 1)then output;
run;

In the space below, enter the line of code that will correctly complete the program (Case is
ignored. Do not add leading or trailing spaces to your answer.).

Ans: BYSUBJID; (should be the answer. But in testing engines for SAS certification site, it gives you the wrong answer when BYSUBJID is given. The correct answer says BYSUBJID;BYSUBJID;

What is the reason?)

[Kurt_Bremser]

The correct answer is

by subjid;

[ttp]

Yes That is the right answer.

But the testing dumps says its a wrong answer.

It shows correct answer is:

BYSUBJID;

BYSUBJID;

I am not sure weather this format is followed in the real certification exam also.

there is an another example:

Which CDISC filename contains the following items? 

• Variable attributes
• Controlled terminology
• Computational methods
Enter your answer in the space below (Case is ignored. Do not add leading or trailing spaces to
your answer.).

Answer: DEFINE.XML,DEFINE.PDF,DEFINE (are we supposed to mention all the 3 for the answer?)

That must be some kind of typo. More than one by statement in a data step results in a syntax ERROR (221-185).
