I wasn't as clear as I should have been, sorry.  That bit, I can do.
Effectively the same as:

VAR_1="I"
VAR_2="pity"
VAR_3="the"
VAR_4="fool."
...

Now what I want to do is loop over the values until "VAR$i" is not set, eg
concatenating them together.

i=1
eval CURRVAL="VAR_${i}"
while [ ! -z $CURRVAL ]
do
      VALUES ="$VALUES : $CURRVAL"
      eval CURRVAL="VAR_${i}"
      i=$(( $i + 1 ))
done

but that doesn't work.
