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.
