Array reference - bad substitution

I've created a series of arrays named as follows:

row1[]
row2[]
row3[]
.
.
.
row10[]

Each has 4 elements.

I'm trying to echo the array elements out in a for loop. Here's what I have:
Code:
for ((i=1;i<=10;i++))
do
  for ((j=1;j<=4;j++)) 
  do
    eval out=${row`echo $i`[$j]}
    echo -n $out
  done
  echo
done

I get the bad substitution error on the eval out= assignment. Oddly, just a few lines before that, almost the exact same syntax works fine for assigning the values to the arrays ( eval row`echo $i`[$j]=......)

Any help is much appreciated.

imap_mime_header_decode - Decode MIME header elements

SYNOPSIS
array imap_mime_header_decode (string $text) DESCRIPTION
Decodes MIME message header extensions that are non ASCII text (see RFC2047). PARAMETERS
o $text - The MIME text RETURN VALUES
The decoded elements are returned in an array of objects, where each object has two properties, charset and text. If the element hasn't been encoded, and in other words is in plain US-ASCII, the charset property of that element is set to default. EXAMPLES
Example #1 imap_mime_header_decode(3) example <?php $text = "=?ISO-8859-1?Q?Keld_J=F8rn_Simonsen?= <keld@example.com>"; $elements = imap_mime_header_decode($text); for ($i=0; $i<count($elements); $i++) { echo "Charset: {$elements[$i]->charset} "; echo "Text: {$elements[$i]->text} "; } ?> The above example will output: Charset: ISO-8859-1 Text: Keld Jorn Simonsen Charset: default Text: <keld@example.com> In the above example we would have two elements, whereas the first element had previously been encoded with ISO-8859-1, and the second element would be plain US-ASCII.
