in reply to Process string as Array

Here's a handy code fragment I was just looking at today. 

$string = 'foo' x 2048;
$n = 1024;    # $n is group size.  
@groups = unpack "a$n" x ((length($string)/$n)-1) . "a*", $string;

print join("\n\n\n",@groups),"\n\n";

    Recent changes to unpack (added in 5.8.0) have made splitting a string into groups much easier. 

    $string = "foo" x 3 . "fo";
print join(" -- ", unpack "(A3)*", $string), "\n";

    Though your code is slightly different; the final "fo" is tacked onto the end of the last element, whereas with the above it's a new element.
