                              SUBMENU—例子

    下面的CONFIG.SYS文件定义了一个主启动菜单和一个子菜单：

    [menu]
    menuitem base_config,Base configuration only
    menuitem full_config,Normal configuration
    submenu netmenu,Normal configuration with network

    [netmenu]
    menuitem lanman,Start Microsoft LAN Manager
    menuitem vines,Start Banyan VINES
~w
    [base_config]
    dos=high
    device=c:\dos\himem

    [full_config]
    include=base_config
    dos=umb
    device=c:\dos\emm386 ram
    device=c:\dos\ramdrive.sys 512

    [lanman]
    include=full_config
    rem Commands for Microsoft LAN Manager would go here。
~W
    [vines]
    include=full_config
    rem Commands for Banyan VINES would go here

    这个CONFIG.SYS文件提供4个配置的选择：基本配置（base_config），全配置
（full_config）和两个网络配置。两个网络配置包含全配置的所有命令：lanman
配置运行Microsoft LAN Manager程序而vine配置运行Banyan VINES网络软件。要
选择一个网络配置，首先应从主菜单中选择项3"Normal Configuration with
network"，然后DOS显示网络选择子菜单。

    DOS启动时，显示如下菜单：
