concatenation

Sorry I don't understand why there is concatenation here. The files are produced as age_11, age_12...

It is concatenating the string that is being sent.  In short, it is submitting:

%break(16)

which will run the macro with the variable's value

Can I ask how '||age||' became the value of the variable?

Thanks for help.
