I could be blind (wouldn't be the first time!), but I don't see the problem with this
code. I
tightened it up a bit to try to reduce the scope of the issue to something more
obvious:
for my $hour ( 1..24 ) {
my $name = "data.hr$hour";
for my $i ( 0..1847 ) {
$specSum{$name}[$i] += $hrHash{$name}[$i];
}
}
That appears to have the same functionality as your original code. It doesn't seem to
have
anything wrong with it. Perhaps the error lies elsewhere? There's nothing wrong with
using
variables as hash keys.
