RPN for max of list of nodes

Hi all,

I currently have a legend formatted like a table like the one below:

               min    max    average
node01   123    123         123
...
nodeNN  123    999         123

I would like a line that displays the maximum for all nodes that looks
something like what follows:

overall max: 999, node NN

              min    max    average
node01  123    123         123
...
nodeNN  123   999         123

Looking at the RPN documentation it looks possible to find the max value
with a CDEF, but is there a way to find the associated node as well?

Thanks,
Aaron
