Reformatting the code, adding comments, removing some unneeded quotes, and adding a pair of missing quotes, the script could be rewritten as:
Code:
# Loop through every file in the current directory with a filename ending in
# "file" setting the shell variable file to the name of one of those files.
for file in *file
do
        # Run awk for one file...
        awk '
        {       # Set the awk variable s to "name" (in quotes) if this is the
                # 1st line from this file; otherwise set it to the name of the
                # current input file (in quotes).
                s = FNR==1 ? "\"name\"" : "\""FILENAME"\""
                # Print the awk variable s followed by the output field
                # separator followed by the current input line.
                print s,$0
        # Set the output field separator to a comma, reading input from the
        # file named by the shell variable file and directing the
        # output to a file named by the shell variable file preceeded by
        # the string "New_".
        }' OFS=',' "$file" >"New_$file"
done

Does this explain what you wanted to know?

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
