Re: Std Dev in RPG

So I have 10 items in an array and I'd like to figure out a mean (average)
and standard deviation. For the mean, I can XFOOT, then divide by the
number of elements in the array. I've only used SQL with tables - can I
use SQL against an array?

Isn't it STDDEV or STDDEV_POP (instead of STD)?
