Thank you bartus, it worked perfectly. But, I cannot decode the logic. Could you please explain this to me?
Few doubts in this:
NR!=FNR --> this is needed because I told that counting of the lines may not be same in both the files? Or this is an indicator to parse the second file? If that so, this explicit indication is really needed to make awk to parse the 2nd file? Please clarify me.
You second guess is correct. NR==FNR means parsing 1st file, and NR!=FNR - second. It can be written differently thought:

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
