Make it DEPTH, SIZE or LENGTH, and you're set, as their name is even more
obvious. (SIZE & LENGTH might be ambiguous in that they could be relative
to the properties of the upper element only)

So, that's for the context... Here comes the hijack :-)

Are there some RRD-compatible RPN lib out there ?

I mean, I'd like to do some computation on the values, but as it'll be
regular, I do not want to trigger a rrdcache flush. That rules out regular
rrd functions.

PS, sorry steve, i didnt sent to the list on the first email...
