Re: uninitialized value in modulus (%)

[ichimunki]

Are you sure that %alphabet contains data? None of the code above shows us how data gets in there... and if data gets in there for likely values of $s.

Is it issuing this warning multiple times for the same run? Otherwise: you get an error the first time through because you never set $alphabet{$s} to anything for its first use, but at the end of your sub, you ++ it, which means that thereafter it has a valid value (i.e. has been "initialized").

Yes, multiple times... I thought i had initialized it by saying: my alphabet; and then it would populate itself automatically...? thank you!
