如清单1所示，变量和诸如循环等脚本控制结构使脚本更容易编写和维护。

As demonstrated in Listing 1, variables and script control structures, such as loops, make scripts easier to write and simpler to maintain.

选项板也包括了控制流所需要的基本编程结构，例如有条件执行的决策点和流程周期的循环。

The palette also includes basic programming constructs that allow for controlling the flow, such as decision points for conditional execution, and loops for process cycles.

There are so many other constructs like loops and conditions and such, so what I thought we do in conclusion today is look at this program.

这里有很多其他结构类型如循环控制,条件分支等等，所以我觉得应该,以这个程序作为结束。
