DOS学习程序 (非常好的模拟DOS程序)纯绿色版

                               GOTO─例子
 
    下面的批处理文件把驱动器A的磁盘格式化为系统盘。若操作成功，GOTO命令
就把MS-DOS定向到“end”标号。
 
    echo off
    format a: /s
    if not errorlevel 1 goto end
    echo An error occurred during formatting.
    :end
    echo Successfully formatted the disk in drive A.

?    echo off
?    format a: /s
?    if not errorlevel 1 goto end
?    echo An error occurred during formatting.
?    :end
?    echo Successfully formatted the disk in drive A.
