Perl For Dummies

In the days before personal computers, BASIC was the easyprogramming language to learn, and serious programmers learnedFORTRAN or COBOL to do “real work.” Today, many peoplehave discovered that Perl is both a great beginning programminglanguage and one that enables them to write powerful programswith little effort.

If you’re interested in discovering how to program (or howothers program), Perl For Dummies, 4th Edition, is for you.If you already know something about programming (but not aboutPerl), this book is also for you. If you’re already an expertprogrammer, you’re still welcome to read this book; you canjust skip the basic stuff (you never know what kind of new tips andtricks you’ll pick up).

This reference guide shows you how to use Perl under manydifferent operating systems, such as UNIX, many flavors of Windows(Windows 95/98, Windows NT, Windows 2000, Windows Me, and WindowsXP), and Macintosh OS 9 and OS X; in fact, Perl runs on many moreoperating systems than these.

• Creating your own Internet clients

The Perl programming language enables you to write fully workingcomputer programs with just a few steps. It’s particularlygood at common programming tasks, such as reading and writing textfiles, but it also excels at reducing the work that programmershave to do. Perl For Dummies, 4th Edition, shows you how todo all of that and how to modify programs to your heart’scontent.
