How exec works

[Olivier Hertrich]

I want create a liste with :

   control:
        list = ( "exec /bin/awk -F: '{if ($4 > 100) {print _ $6}}'
/etc/passwd"  )

   If I try to see the list in a shellcommand like :

        any::
            echo $(list)

I see the string  exec /bin/awk -F: '{if ($4 > 100) {print _ $6}}'
/etc/passwd and not the result of the command.
Where I'm wrong?

Thank You.
