Thank you for pointing out the perl test. I just read it expecting to answer about 10-20 correctly. Imagine my joy when I correctly answered 42 of them. I guess the books are working for me. The monestary gets a lot of the credit too.
I got number 41 correct, but I see where one of the monks said it would not work, so I guess I'm confused too. Also, I answered fork instead of system to 25, so I have a little more studying to do in that area. Thanks again.
