Character pointers
The fundamental types PAnsiChar and PWideChar represent pointers to AnsiChar and WideChar values, respectively. The generic PChar represents a pointer to a Char (that is, in its current implementation, to an AnsiChar). These character pointers are used to manipulate null-terminated strings. (See Working with null-terminated strings.)

字符指针
基本类型PAnsiChar和PWideChar分别表示指向AnsiChar和WideChar类型值的指针。一般类型PChar表示指向Char类型（当前实现中是对AnsiChar）值的指针。这些字符指针用于操作空结束串。（见空结束串。）
