Wirhout the double quotes nothing gets loaded into the array.. Also 
nothing gets loaded into the array with my original code, as the output 
thst I thought ewas being generated by that function, was actually being 
output by the following function which works very nicely. I had 
forgotten to comment out it's call in my test code so it was generating 
the loop output before the only output of the first function I quoted 
which was the error message.

# Test array assignment from variable line by line
function ReadintoArray {
     PackageData=`dpkg -p gedit`
     LoopCount=0
     while read ThisLine; do
           Data[$LoopCount]="$ThisLine"
           echo "$LoopCount - ${Data[$LoopCount]}"
           (( LoopCount++ ))
     done <<<"$PackageData"
}

I guess I'll go with this second version which works great, unless 
someone can tell me how to load the array with a single call like I was 
trying in the other function. Just looking for the most efficient way to 
get the data into the array line by line.
