I think you want to declare String to be a CHARACTER variable. Currently, it is a numeric variable. To declare a character variable, put a '$' symbol after the name of the variable on the INPUT statement, like this:
Input string $ 7.;
After making that change, rerun the program and examine the output. Let us know if you still have questions!
What determines `pos`? Please provide some example data.

What is your question?
Your task can be much easier solved by using the right tool (Maxim 14), which is the SCAN function:
data a;
input string $7.;
last_word = scan(string,-1,"., ");
cards;
ABC.DEF
