[thelist] Perl string help

Brilliant! However, I'd make the slight modification
	$start += $split+1;
to drop the space itself.

Note that this presupposes that all spaces are single. You might want to
	$text =~ s/ +/ /g;
or even
	$text =~ s/\s+/ /g;
at the beginning to make sure that's true.

I am not a Perl guru but...

assuming $text contains the text you want to split up then the
following should work. At the end you'll have an array (@pieces)
which contains all the pieces.

my $piece_length = 250;

my @pieces;
my $start = 0;

while ( ( length($text) - $start ) > $piece_length ) {
    my $split = rindex( substr( $text, $start, $piece_length ), ' ' );
    push @pieces, substr($text, $start, $split);
    $start += $split;

push @pieces, substr($text, $start);
