selecting lines using awk

I have a file which contains five hundred thousand lines (500,000). I want to select lines of every 1000 lines from that file using AWK. I can think something like this in bash as below:

for lines in {0..500000..1000}
do
........
........
done

But I want to use AWK. I do not know how to construct in AWK and unfortunately I could not find example in online.

I appreciate if anyone could help.

Thank you.
Vijay

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
