Passing argument to system call in awk script

So, I have this script. It reads a CSV file that has a mixture of object names with IP addresses (parsing out that part I have working), and object names which have a DNS name. I want to be able to run a "dig +short" based off of the name given to me in the line of the awk script, and then deal with that as it comes. (Ideally, for things where dig returns more than one IP, I'll be able to say object_1 xxx.xxx.xxx.xxx, object_2 xxx.xxx.xxx.yyy, and so forth.)

Code:

#!/bin/bash
cat  $CSV | egrep -v "Network Entity" | awk -F, '
        {for (i=1;i<=NF;i++)
                {if (some conditions) )
                        { Bunch of commands which are working fine}
                          
                else
                      {if (($i == "Network address") && ($(i+1) !~ /[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+/))
                          {
                               #print the object name
                               {printf $1 ","};
                               #Use the object data to run dig
                               {print system("dig +short" $(i+1);}

                          }

                      }
                
                }
        }' > $HOSTS_AND_SUBNETS

I'm getting a syntax error. How do I pass an argument to a system call?

Thanks in advance,
Mike

face(1)                                                            User Commands                                                           face(1)

NAME

       face - executable for the Framed Access Command Environment Interface

SYNOPSIS

       face [-i init_file] [-c command_file] [-a alias_file] [filename...]

DESCRIPTION

       The  Framed  Access  Command  Environment Interface (FACE) presents your files and file folders on the screen through a system of menus and
       forms if you are properly set up as a FACE user.

       filename must follow the naming convention Menu.xxx for a menu, Form.xxx for a form, and Text.xxx for a text file, where xxx is any  string
       that  conforms  to  the  UNIX   system  file  naming conventions. The Form and Menu Language Interpreter (FMLI) descriptor lifetime will be
       ignored for all frames opened by argument to face. These frames have a lifetime of immortal by default. If filename is not specified on the
       command line, the  FACE Menu will be opened along with those objects specified by the
        LOGINWIN environment variables. These variables are found in the user's .environ file.

OPTIONS

       The following options are supported:

       -a alias_file           Alias file

       -c command_file         Command file

       -i init_file            Initial file

OPERANDS

       The following operand is supported:

       filename        The full pathname of the file describing the object to be opened initially.

EXIT STATUS

       The face command will return a non-zero exit value if the user is not properly set up as a  FACE user.

FILES

       $HOME/pref/.environ
