I changed 98 to DOS using your method, but I want to be able to choose at startup whether to enter DOS or 98, so I added this to AUTOEXEC.BAT: choice /c:dw Dos,Windows if errorlevel 2 echo Welcome To Dos! if errorlevel 1 win But no matter whether I press D or W, it only enters 98. What should I do? Sorry to trouble you

if errorlevel 1 win should be changed to: if errorlevel l if not errorlevel 2 win

@ECHO OFF PROMPT $p$g set temp=%ramd%:\ set tmp=%ramd%:\ path=o:\;%RAMD%:\ choice/c:evrn please press if errorlevel 4 goto ndd if errorlevel 3 goto pv if errorlevel 2 goto kv if errorlevel 1 goto end :Ndd LH Ndd.exe goto end :pv FINDRAMD>NUL set path=%ramdrive%\;%path% %ramdrive% CD \ LH PVIEW goto end :kv FINDRAMD>NUL set path=%ramdrive%\;%path% %ramdrive% CD \ LH kv3000 goto end Look at this file—what do you think your file is missing?

Although I've read the batch programming article written by the boss, I still don't really know how to use it Is my file missing subroutines?

I just changed it to choice /c:dw Dos,Windows if errorlevel 2 goto win if errorlevel 1 goto dos :win win :dos echo Welcome To Dos!!! It worked ^_^!! But I still don't quite understand why??

Changing it to: if errorlevel l if not errorlevel 2 win works. Because ERRORLEVEL 1 actually means ERRORLEVEL >=1 Master Rushi made this mistake just now too!
