在DOS下我想得到运行某一个文件后的返回码如GHOST，怎样使用err2env?
如用COMMAND /Z后，运行GHOST后它会返回码0的。

实际您可以用BAT文件来实现的，以下是我编写的一个批处理文件，此文件用于显示程序运行后的退出码，请看：

@echo off
REM 此处将您要的运行的程序名写上
for %%a in (0;1;2;3;4;5;6;7;8;9) do if errorlevel %%a set testerr=%%a
echo.
echo Current errorlevel is : %testerr%
echo.
set testerr=

有什么不妥之处请大家指正！

顺便问个没明白的问题:既然REM为程序加注解不运行,那么不写这行不完了吗? 加与不加的区别在哪儿呢? 谢谢...!

注解只是让自己和大家看得更清楚一些嘛。。比如有时想修改源代码时这样就更加直接易行了。

版主，我是想请教err2env这个软件的具体用法，看英文说明又看不懂，能具体指点吗？

能把ERR2ENV这个软件上传吗?也好让大家看一看提示信息.

Kinglion：网站的“脚本工具”中有ERR2ENV下载的：

版主，“err2env”这个软件能在PC-DOS7.1中用么？具体怎么用？

不好意思，我的E文太次了，只好将帮助文件上传，请E文好的大侠们帮忙翻译一下了。
好象软件的作者是华裔的！

ERR2ENV will mainly set the current errorlevel to an environment
parameter (default to ERR_LEVEL). Whenever it is run in a new DOS
version for the first time, it will work out the actual address
of the errorlevel for the new version and then store it back to the
program, so that it will be able to run instantly next time.

ERR2ENV tries to avaid DOS batch's clumsy way of finding out the
current errorlevel.

ERR2ENV.ZIP contains the following files

readme - this file
err2env.exe - set entry errorlevel to environment parameter
err2env.c - the C source code

?FORMAT: ?

I. err2env ]
II. err2env "/qn鄕#+#-#t#" ]
where # represents an positive integer

Format I is the usual application format. All options must be
contained in a single string:

q - quiet with no non-critical messages
n - environment parameter ERR_LEVEL will not be changed
x# - exit with errorlevel specified by #
+# - exit errorlevel will be the entry errorlevel plus #
-# - exit errorlevel will be the entry errorlevel minus #
? - remove stored errorlevel addresses from ERR2ENV.EXE.
ERR2ENV.EXE can store addresses for upto 100 DOS versions,
when that is run out (possible?), we can use this option
to clear off the old version addresses to make space
for the new ones. But this is quite unlikely, so this
option should perhaps never be used.
,env - set errorlevel to the environement parameter specified
by "env"

The order of above options are interchangeable and duplicable.

Format II is essentially to be called by ERR2ENV.EXE itself. In this
format, the first three option characters must be "\".
The program will then read addresses from filein and
write those back to fileout if the values specified by
the address agrees with the value given via /t#. This
algorithm is influenced by George A Theall's method in
ERRLVL12.ZIP

Examples:
ERR2ENV /nqx25
quietly set errorlevel to 25, env para ERR_LEVEL not changed
ERR2ENV /-1,oldlevel
set OLDLEVEL to current errorlevel, say 99, exit with
new errorlevel 98, and display message: errorlevel=(99->98)
