Perl技术内幕(中文版，英文最后三章，书中源码）

You'll find the code from the book in these directories, arranged by chapter. There are two versions of all source code - one in the DOS subdirectory and one in the Unix subdirectory for each chapter. The only difference between these versions is how the text is formatted. The DOS version of each source file uses a carriage return/line feed at the end of each line, as is standard in DOS, and the Unix version uses a newline character (only) at the end of each line, as is standard in Unix. I've provided both versions to let you choose the version best suited to your editing program. Besides this difference, the two versions of the source code files are the same. There is no special preparation needed for installation, just copy the files you want to use to your hard disk. The file codeXX, where XX is a chapter number, contains the code from Chapter XX. To run a specific example from Chapter XX, copy and paste the appropriate code from codeXX to a new file and run that new file using Perl. Note that in some cases you should update file paths or URLs in the code before execution - see the book for the details. Enjoy working with the code - and happy programming!
