begin block造句

• In the begin block , we initialize our integer variable
  在begin块中，将整数变量
• We used a begin block in the previous example
  程序输出如下，这正是我们所期望的：
• In pl 1 , a begin block or procedure block
  1语言中的开始块或过程块。
• For such situations , awk allows you to define a begin block
  这意味着如果希望任何文本从新的一行开始，那么需要明确写入
• We ll start off with the first line , the begin block and a function definition
  我们将从第一行（ begin块和函数定义）开始：
• Begin blocks , for instance , will be executed first but can be specified many times throughout the program
  例如， begin语句块会被首先执行，但它可以在程序中多次说明。
• The remaining lines define our begin block , which gets executed before awk starts processing our checkbook file
  其余行定义了begin块，在awk开始处理支票簿文件之前将执行这个代码块。
• Because the begin block is evaluated before awk starts processing the input file , it s an excellent place to initialize the fs field separator variable , print a heading , or initialize other global variables that you ll reference later in the program
  Awk还有" do . while "循环，它在代码块结尾处对条件求值，而不象标准while循环那样在开始处求值。它类似于其它语言中的" repeat . until "循环。
