The text-string " swap " could be any other. BTW I am not a pro so: I do not know anything about circular buffers, excuse me.
My OS here is debian wheezy 7.5, no server.
So I cut out the first statement do direct it after the awk-statement to the stdout. As you may see, this could be a beginner, but I assure you I am right in the middle, because this is my third week around with awk.
We don't care if you're a beginner. As long as you want to learn, we want to help you.
But, to help you we need to understand what you're trying to do.

Show us a sample of your input file. Give us details about the format of this file, the size of the file, the field separators in the file, etc.
Explain to us in detail in English what you want to do to that input.
Show us a sample of the output you want your script to produce.

IGAWK(1) Utility Commands IGAWK(1)
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
