coding output question

[clq]

Why is the answer 8 instead of 3 observations? Shouldn't it be 3 since there are 3 A's?

conditional explicit ouput=      3 

unconditional explicit output=5

Total=                                     8

That's a trick. You read too fast and didn't see the *2* output statements.

/* Think of the code as follows */
data WORK.ONE WORK.TWO;
   set WORK.INPUT;
  if Var1='A' then output WORK.ONE;
  output /* to both WORK.ONE and WORK.TWO */;
run;

1) create the data set(s).

data work.input;
   input var1 $ var2 $;
datalines; 
A  one
A  two
B  three
C  four
A  five
;
run;

for example.

2) run the code.

3) examine the results.

4) figure out which bit you missed along the way to the answer.

You'll learn a lot that way.
