前言
实际上每章的内容并不多，我们把它控制在一两个小时内能够读完的篇幅。每章后面
都附有若干习题，帮助你巩固刚学到的知识，在附录
A
中还附有习题解答，供你比对
参考。因此本书可说是相当适合作为“
Perl
入门”的课堂教材来使用。我们对此有第
一手的实践经验，几乎所有内容都是逐字逐句从我们的“
Learning Perl
”课程教学中

是活生生的“

Strawberry Perl
（

）以及许多其他流行的
Perl
版本。

基础，但我们还是衷心希望你能够对写程序的
基本概念有所了解，像变量（
variable
）、循环（
loop
）、子程序（
subroutine
）和数
组（
array
）以及最重要的“用你最熟悉的文本编辑器来编辑源代码”这类事情。我们
不会花时间说明这些概念。有些人学的第一个程序语言就是
Perl
，并因学习本书而获
得成功。我们很高兴能看到这样的事例，但无法保证每个人都一样，请不用多虑，只 ...
