Need help using awk command

Hello,
I am trying to print a formatted test using awk command and its not working for me:

for ex: there is one file matching the pattern test as shown below

Code:
$ ls -ltr test* | awk '{print $9}'
test.dat

now, I want to print to a file the test file_name: test.dat using awk like
Code:
$  FLAG=file_name
$ls -ltr test* | awk '{print "$FLAG",$9}'
$FLAG test.dat

In the above awk command, I want to print the value of variable FLAG which will have some value (set above to file_name, this value can change at runtime) but I am not able to print it as it prints the variable name and not its value.

Any help is appreciated. Txs.

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
