Please use code tags for code fragments.

Your code is pretty much straightforward:-
Code:
# BEGIN Block
BEGIN {
        i = 1                           # Initialize i = 1
        file = "modified.txt"           # Initialize file = modified.txt
}
{
        if ( $0 !~ /^DS:/ )             # If record does not start with DS:
                print $0 >> file        # Write record to modified.txt
        else                            # If record does start with DS:
                print "DS: ", i >> file # Write DS: i value to modified.txt

        if ( i == 8)                    # If i value == 8
                i = 1                   # Reset i value to 1
        else                            # If i value != 8
                i++                     # Increment i value by 1
}
