Difference in positions

[light]

 Hello 🙂

There is a statement: "Apple is the Anthem"

How do I write a step that finds the difference in positions between the two As? 

THANK YOU!!!!

Well, you could use the index function to find each A and then subtract but that doesn't scale well. 

Will you always be looking for two As?

It looks like your doing string functions. You may want to review the available functions here

Just two A ?

data _null_;
x="Apple is the Anthem";
a=findc(x,'A');
b=findc(x,'A','b');
dif=b-a;
put a= b= dif=;
run;
