<code>
@array = (5,5,null);
$array[2] = $array[0] * $array[1];
print "$array[2]\n";
# output 25
$array[0] = 10;
print "$array[2]\n";
# output 50
</code><pre>
if you know your code, you know that second
output statement is false.
you must re-calculate the value in $array[2] to
get the output to come out as '50'
does anyone know of a way to make $array[2]
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 $array[2] 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.
