Awk: What is the difference between: X[a,b,c] - X[a][b,c] - X[a][b][c]

I'm using a three dimensional array. There seems to be a significant difference to how awk - GNU Awk 4.1.4, API: 1.1 (GNU MPFR 3.1.5, GNU MP 6.1.2) - treats the following:
What is the difference between these? Where can I find it documented?
To demonstrate, with a small piece of code:
$ awk -f demo.awk </dev/null
As the code says, in the last example, if I try
which seems the correct syntax, it gives the error

Hello again,
I've run into another problem that I've been unable to solve. With everyone's help last time, the script worked perfectly! This problem takes a little more finesse, and the bash script I thought up didn't work, so I've canned it. I'd like to try awk if possible. Here's my... (6 Replies)

Hi,
I've got what is probably quite an easy little (presumably) awk problem that I just can't seem to work out (mental block...I've already spent ages getting the data into this format!). I want to work out the difference between rows for certain columns. for example:

In the awk I am trying to subtract the difference $3-$2 of each matching $4 before the first _ (underscore) and print that value in $13.
I think the awk will do that, but added comments. What I am not sure off is how to add a line or lines that will add sum each matching $13 value and put it in... (2 Replies)
