awk loop using array:wish to store array values from loop for use outside loop
Here's my code:
What I would like to do is store each iteration value of the variable snr currently defined as:
to be used in the following line:
So that when it goes through each of the matched ^sta EP values it uses the correct value of the loop to insert into the above line. Does this make sense? Currently, since I'm not sure how to store these values it only retains the last value of the loop, which makes sense because I'm not telling it otherwise. My question is how do I store that value and then call it later in the line above? 'a' is already an array from the match statement, but I'm not sure if I need to make snr also be an array, or what to do. Any help would be greatly appreciated! Thanks in advance!
