I, also, am a bit unsure of the real question of rthawkcom.

However, if it has to do with the fact that the  @out array has all the values of the  %hash when  $_; is the last statement executed in the map block and has a few empty strings in place of hash values when  $_; is not the last statement, I think I can explain.

The value of the  map block on each iteration will be the value of the last expression evaluated in the block. This is always the  $_ expression, previously set to a hash value, when the  $_; statement is last.

When the
    if($_>$max){$max=$_}
statement is last,  $_>$max will be the last expression evaluated when  $_ is less than or equal to  $max (and it will evaluate to the empty string, or false).

When  $_ is greater than  $max the  $max=$_ true clause of the statement will execute, which evaluates to  $_ previously set to a hash value.

Update: This reply is essentially the same as jethro's.
