Here the END part is trying to do a scanning on the array of input being built in the action panel of gawk

Code:
gawk '/pmd/ { 
split($1,IP," "); 
x[IP[2]]++; 
y[n++]=IP[2]"--"$2;} END {
for(i in y){
{
{print y[i]}
}
}
}' file

other approach was

Code:
gawk '/pmd/ {
split($1,IP," "); 
x[IP[2]]++; y[IP[2]"--"$2]++;} END {
for(i in x){
 for(j in y){
if(i ~ y){
print i}
}
}
}' file

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
