If the strings you want to obtain follow a pattern (i.e. clientr.stat_<whatever>), you can use getstringkeys(start).
getstringkeys() returns the suffix of all variables beginning with 'start'.
For example, if I have:
clientr.zomg_hp = 3
clientr.zomg_rawr = lawl
clientr.zomg_pi = 3.14something
temp.keys = getstringkeys("clientr.zomg_");
temp.keys will be an array containing the strings {hp,rawr,pi}
It's really useful.
