You need to have a command in your script that can receive the pipe, like read.
I concocted this:
Code:
if ! [ -t 0 ]; then  # if stdin is not a terminal
  read params
  set -- $params
fi
echo $1
echo $2

Code:
 ./test  555 123
555
123

Code:
$ echo 555 123 | ./test
555
123

In this example the pipe overrides the command line parameters, but you can change that of course..

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

       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
