G'day perlynewby,

"question 1 I don't understand why on INDEX, the warning says $string is undef? and I also had to declare it again as "my" when I did on pragma."

When you get a error (or warning), it's vitally important that you paste it verbatim, not just type in a vague facsimile of the message.

I strongly suspect that the error you got didn't mention $string at all; instead, it made reference to $tring! (Note the missing 's'.)

So, to fix, add the 's' and remove the my (which you added).

"question 2 whys is the '~~" operator method it's not working"

That's the smart-match operator. It's experimental and subject to change. I recommend you learn non-experimental Perl before delving into ~~.
