in reply to Dynamic Hash value

You can create scalar references to $ini and $last, and use these references in your %results hash. Then when you change the values of $ini and $last, the hash will refer to the changed values. Read up on references here - perlref
my $ini = 5; my $ini_ref = \$ini; print $$ini_ref; # outputs 5 $ini = 6; print $$ini_ref; outputs 6

    no in this case it's not that simple because the scalars are not only referenced but also part of a calculation.
