conditional statements

Hello,

Are below two DATA step (test1, test2) same ? I am assuming the NOT FIRST.ID is implied in test2.


data test;
 input id x;
 cards;
 1 2
 1 2
 2 3
 2 2
 ;
 run;

data test1;
 set test;
 by id;
 retain val;
 if first.id then val = 1;
 else if not first.id and x > 1 then val = 5;
run;

data test2;
 set test;
 by id;
 retain val;
 if first.id then val = 1;
 else if x > 1 then val = 5;
run;

Yes, because the only way to enter the second condition is if it's not first.ID.
