Do you want the extracted age to be character or numeric?

Are you being forced to use the tools you mentioned? They're not the best ones for the job. Using those only might force you to assume that the age is always two digits long.

length() is not needed and actually dangerous (think of kids and centenarians).

Use anydigit() to find the first occurence of a digit, and substr() from there.

Hi Vishal,

Age=input(substr(nameage,length(nameage)-1),8.);

In this way you can use substr and length function both.If you are sure about that age is coming as a last 2 digit.

I want age in numeric, yes only for this scenario age is only two digit long.
