For example you can put something like this in your script `END{for(i in a)printf"a[ %s ] = %s\n",i,a[i]}` to list the indexes and values in array a. As with you current code $0 is already listed in the output just above `END`, should be clearly visible what to use as array index to get the corresponding values.
Jun 20, 2013 at 16:33	comment	added	pogibas		OK, when we says `$3 in a` it puts `f2 $2` into that position, hence to print it we have to say "print position `$3`".
Jun 20, 2013 at 16:30	comment	added	pogibas		So we are saying: `a[$1]` - put in array `f2 $1`; if `f1 $3` is in array (that is `f2 $1`), then print. But 1) why do we need `=$2` ; 2) How do we make `f2 $2` encoded as `a[$3]`?
