If an individual set option that is affected by a shortcut set statement is explicitly set after the shortcut set statement is issued , the individual set statement overrides the corresponding shortcut settings 如果在发出快捷set语句后显式设置了受快捷set语句影响的单个set选项，则该单个set语句将覆盖相应的快捷设置。
For example , even if the set statement is in an if . else statement block that is never reached during execution , the set statement still takes effect because the if . else statement block is parsed 例如，假设set语句在if . . . else语句块中，而在执行过程中从未到达过该语句块，但由于分析了if . . . else语句块，因此set语句仍生效。

When a global or shortcut set statement , such as set ansi defaults , sets several settings , issuing the shortcut set statement resets the previous settings for all those options affected by the shortcut set statement 当全局或快捷set语句（如set ansi _ defaults ）设置多个设置时，发出快捷set语句后，将重设所有受该快捷set语句影响的选项的先前设置。
