Typically, the setup function contains the size function (to define the bounds of the window) as well as initialization of variables that are used during operation.
通常，setup函数包含size函数(用于定义窗口的边界)以及在操作期间要使用的变量的初始化。
Since Perl doesn't have memory allocation issues, the biggest source of bugs for me has been the improper tracking of counter variables (wrong initialization, wrong increments, or wrong bounds).
由于Perl没有内存分配问题，所以对我来说缺陷的最主要来源就是追踪计数器变量的错误(错误的初始化，错误的增量，或者错误的边界)。
The initialization can occur when the typed array variable is declared or later, as with variables of other types.
这种初始化可能发生在具型别阵列变数被宣告时或是稍后和其他型别的变数一起宣告时。
