In your example, each entry will have it's own counter:

Code:
counter (a) = 3, because "AAA BBB CCC DDD EEE" incremented 3 times
counter (b) = 2, because "PPP QQQ RRR SSS TTT" incremented 2 times
counter (c) = 1, because "VVV WWW XXX YYY ZZZ" incremented once
counter (d) = 0, because "GGG HHH III JJJ KKK" did not increment at all

And based on the counter value, some actions will be triggered.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
