[Xerte] Re: sum part of array?

[Dave Burnett]

I'll add it to my wish list. :-)
It's just a small array so for now looping doesn't bug me too much.
Maybe when I need an industrial strength solution.  
Thanks Jules.

Ah, could do.


But this is getting uglier than I thought.

e.g. my_array.sum(0,3);


That kind of thing.
Looks like no.
