Interview Question to my friend.

 

x=A,B,C,D,E,F,G ;

He wants  to find 4th  comma or 5th comma.

 

I have given this answer.

data a;
x='A,B,C,D,E,F';
run;
%let p=9;
data find_comma;
set a;
fouth_comma=find(x,',',&p);
run;

Is it correct? or wrong?

Interview asked me to write dynamically. 

Please correct if I'm  wrong.

They want dynamically?
