||
| 7 | 它返回串内被定义的 $emph value$emphend； |
||
| 8 | 如果串内出现 $emph name$emphend 但后面没有 $emph =$emphend 号, |
||
| 9 | 则返回 $emph name$emphend 本身; |
||
| 10 | 如果 $emph string$emphend 内找不到 $emph name$emphend, 则返回空串. |
||
| 11 | <p> |
||
| 12 | $emph value$emphend 可以是多个词组成的串, 只要它们被一对圆括号, 方括号, 花括号 |
||
| 13 | 或双引号括起来. 在输出时, 这些定界符被抛弃. |
