(350 . <图元名: 7ef87ef8>) (3 . "22") (350 . <图元名: 7ef87f00>))
(dictremove ename symbol)
功能及参数
此函数将在字典 ename 中删除一个 symbol 项目。
ename 参数是一个指定要寻找的字典图元名。而symbol参数则是要删除的关键名称。如果删除失败, 则系统将返回 nil。
若返回成功, 则系统会返回所删除的项目名称。
一般说来, dictremove函数并未真正自字典数据库中将指定项目删除(仅删除关键符号), 如要真正自数据库中删除,
请搭配 entdel 函数使用。

(dictremove ename symbol) 
功能及参数 
    此函数将在字典 ename 中删除一个 symbol 项目。 
    ename 参数是一个指定要寻找的字典图元名。而symbol参数则是要删除的关键名称。如果删除失败, 则系统将返回 nil。 
    若返回成功, 则系统会返回所删除的项目名称。 
    一般说来, dictremove函数并未真正自字典数据库中将指定项目删除(仅删除关键符号), 如要真正自数据库中删除, 
    请搭配 entdel 函数使用。
