I've got a problem. I scripted a nice guestbook script. All working fine,

tried a lot, but still getting some errors. So, I thought, adding

Which will print something like:

were you scared?

No, it's not hard. vec and ord are simply used for translating ASCII
characters to their corresponding characters, well, let's say, numbers.
Say like %20 represents a space. Anyway, check out:
perldoc -f vec
perldoc -f ord
It's really simple :)

Using the 'x' operator, you can use spaces in your matching pattern:
m/^[a-zA-Z]{0,20} [A-Za-z]{0,20}$/x

Ofcourse, the +,?,* and so on could be used also for determing the character
