A very good point. Mine did not save alot. I did make one more stab, though i doubt it will out-run tye's regexp :
(look ma, no regexp)
# Code by itself :
sub mz2 {
    $c = substr($string,0,201);
    $a = rindex($c,' ');
    ( $a == 201 ? $string : substr($string,0,$a));
}

## Bench addition :
MZS2      => '($chunk) = &mz2()',

## Bench output :
C:\WINDOWS\DESKTOP>perl index
Benchmark: running Hofmator, MZS2, MZSanford, japhy, tye, each for at 
+least 3 CPU seconds...
  Hofmator:  4 wallclock secs ( 3.07 usr +  0.00 sys = 3.07 CPU) @ 378

       tye:  4 wallclock secs ( 3.02 usr +  0.00 sys = 3.02 CPU) @ 514

As expected, no better. But, worth the excersize. I did a quick test to make sure the output was the same, though, i would normally use a regexp, as it would be clearer in most cases than all this oddness. I do not know if this will work on all input cases, you milage may vary, etc, etc, etc ...
