Enumerated types
An enumerated type is stored as an unsigned byte if the enumeration has no more than 256 values and the type was declared in the {$Z1} state (the default). If an enumerated type has more than 256 values, or if the type was declared in the {$Z2} state, it is stored as an unsigned word. If an enumerated type is declared in the {$Z4} state, it is stored as an unsigned double-word.

枚举类型
如果一个枚举类型不超过256个值并且在编译指示 {$Z1} 状态（缺省的）下被声明，那么它被存储为一个无符号的单字节（8位，即1字节）。如果一个枚举类型超过256个值，或在编译指示 {$Z2} 状态下声明，那么它被存储为一个无符号的单字（16位，即2字节）。如果一个枚举类型在编译指示 {$Z4} 状态下声明，那么它被存储位一个无符号的双字（32位，即4字节）。
