Is it possible to re-assign the variable form the loop?

Good day, everyone!
I've got a small problem with re-assigning the variable form the loop. What I'm trying to do is:

#!/bin/bash/
VAR1="AAA"
VAR2="BBB"
VAR3="CCC"

for WORD in VAR1 VAR2 VAR3;
do 
$WORD="DDD"
echo $WORD
done

:o
That's the output and error messages:

-bash: VAR1=DDD: command not found
VAR1
-bash: VAR2=DDD: command not found
VAR2
-bash: VAR3=DDD: command not found
VAR3

I'd really appreciate if anybody could explain how to perform such operations.

Thank you in advance for any suggestions

You will need to use "eval".

Thanks a lot!!!!! I got it!!!
