Never change horses. If you use awk, try to do as much as possible in it (like Yoda's approach). If you start with shell scripting, try to stick to it. It is possible in shell, assuming filearray ist assigned from token.txt:
Code:
while read TOKEN REST
  do for ((i=0; i<${#filearray[@]}; i++))   
     do     [ "$REST" != "${REST/${filearray[$i]}/}" ] && echo ${filearray[$i]} $TOKEN
     done
 done <flat.txt
abc 123
der 234
xyz 345

And, don't open and read flat.txt several times. Memory access is far faster, so loop the array several times.

ip-token

IP-TOKEN(8)							       Linux							       IP-TOKEN(8)

NAME

       ip-token - tokenized interface identifier support

SYNOPSIS

       ip token { COMMAND | help }

       ip token set TOKEN dev DEV

       ip token del dev DEV

       ip token get [ dev DEV ]

       ip token [ list ]

DESCRIPTION

       IPv6 tokenized interface identifier support is used for assigning well-known host-part addresses to nodes whilst still obtaining a global
       network prefix from Router advertisements. The primary target for tokenized identifiers are server platforms where addresses are usually
       manually configured, rather than using DHCPv6 or SLAAC. By using tokenized identifiers, hosts can still determine their network prefix by
       use of SLAAC, but more readily be automatically renumbered should their network prefix change [1]. Tokenized IPv6 Identifiers are described
       in the draft [1]: <draft-chown-6man-tokenised-ipv6-identifiers-02>.

   ip token set - set an interface token
       set the interface token to the kernel.

       TOKEN  the interface identifier token address.

       dev DEV
	      the networking interface.

   ip token del - delete an interface token
       delete the interface token from the kernel.

       dev DEV
	      the networking interface.

   ip token get - get the interface token from the kernel
       show a tokenized interface identifier of a particular networking device.  Arguments: coincide with the arguments of ip token set but the
       TOKEN must be left out.

   ip token list - list all interface tokens
       list all tokenized interface identifiers for the networking interfaces from the kernel.
