A string is some amount of text. Examples of strings are:
"My left foot" "436" "A man without eyes, saw plums in a tree. He neither ate them nor left them; now, how could this be?"
We enclose a string in quotation marks, to indicate where the string begins and ends. The quotation marks are not actually part of the string. (Strings can contain almost anything, including line breaks and even quotation marks -- although you have to be careful with quotation marks so you don't confuse the computer.)
Tinkering with Perl is a free book that provides an introduction to programming in Perl, as well as a basic reference for things like foreach in Perl, if-then, and if-then-else, in addition to providing a glossary where you can find definitions for concatenate and other terms.
Tinkering with Perl may be one of the most popular offerings on this site, but it's not the only attraction. You can read a tongue-in-cheek Game Review: Meatspace, read an even more offbeat customer service survey (whether or not you actually fill it out), and spend a few minutes wishing your boss would read, The Administrator Who Cried, "Important!" (Not to mention that there are other things you can read here besides tech stuff, from Janra Ball: The Headache to The Spectacles.)
