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

[Peng Yu]

Hi,

"input" is a hash of hash. The following example is a nested loop
assuming there are only "1" "2" and "3" in the first level of the
hash. If there are an arbitrary number of elements in the first level,
what is the best way to construct a nested loop? Thanks.

  for(j1 in input[1]) {
    for(j2 in input[2]) {
      for(j3 in input[3]) {
# do something
      }
    }
  }
