Re: [bug-gawk] nested loop of arbitary number of elements in a hash of hash

I'm not sure what you're asking. But I think what you want is
not a nested loop, but rather a traversal of the full multidimensional
array. There is a an example of doing this in the manual, using
isarray() and recursion.  See there.
