gawk - How to loop through multidimensional array?
I have an awk script that I am writing and I needed to make use of a multidimensional array to hold some data... Which is all fine but I need to loop through that array now and I have no idea how to do that.

for a regular array, the following works:

Code:
ARRAY[NUMBER]
for(var in ARRAY) {
  ...
}

but I get syntax errors if I try the following:

Code:
ARRAY[WORD][NUMBER]
for(var in ARRAY[1]) {
  ...
}

syntax error at or near [

How can I loop through a multidimensional array?

---------- Post updated at 09:37 AM ---------- Previous update was at 09:31 AM ----------

Upon further thinking I just created a new variable to mark how many elements were in the second index in the array. If there is a way to loop through the array without having to do that I would like to know.

Thanks,
