data outset; set inset (obs=10); where X=Y;
Does this code logic mean:
Select the first 10 observations from inset and select WHERE X=Y from those 10.
OR
Select observations from inset and apply WHERE X=Y until 10 observations have been selected.
I assume the former but there is an ambiguous question/solution in the Base Programming 2 course that is throwing me off:
3. Read only the first 10 observations satisfying the WHERE statement.
set orion.order_fact (obs=10); where year(Order_Date)=2009;
This: Select observations from inset and apply WHERE X=Y until 10 observations have been selected.
If you have access to SAS, it is a lot faster to test yourself than to ask here, and a much better way to learn as well, by doing.

Compare test1 with test2
data test1;
set sashelp.class(obs=1);
where name = "John";
run;
proc print data=test1; run;
data test2;
set sashelp.class(obs=1);
run;
proc print data=test2; run;
If the WHERE condition was applied after the observation count, test1 would be empty.
