Yes, Rob, you are absolutely correct. Unfortunately, I still lack
confidence in my coding abilities, so when something doesn't work, I
seem to assume I just don't know how to do it properly. In reality, I
just made a dumb mistake, which is partially where this lack of
confidence comes from. :)
What I did was closer to this:
my $i = 0;
while (EXPR) {
$hash{KEY}{$i} = $something;
$i++;
# ok, so now let's test that I did this correctly
print $hash{KEY}{$i};
}
As you can see, silly me put my print statement AFTER I incremented the
variable, so of course that key was undefined. Geez.
Precisely why I'm still on the "beginners" list. :)
Thanks James and Rob for helping me find that my error was not in syntax.
