Buckaroo Buddha has asked for the wisdom of the Perl Monks concerning the following question:
@array = (5,5,null); $array = $array * $array; print "$array\n"; # output 25 $array = 10; print "$array\n"; # output 50
if you know your code, you know that second output statement is false. you must re-calculate the value in $array2 to get the output to come out as '50' does anyone know of a way to make $array2 update itself automatically? i should warn you not to pop a blood vessel trying to answer this for me ... i'm reasonably convinced that i will simply update $array2 on every pass of the loop but for interest's sake i'd like to know if i can do it the way i'd like to.
