AW: [Mono-list] Windows: Propagating exit codes in .bat files?

[Mike Krueger]

Hi

Isn't EXIT a build in commando in the CMD.EXE and COMMAND.COM therefore 
it isn't possible thats not there.
You're right that the Win9x have no /b switch (I've not seen a Win9x 
machine for years :( ). According to some documentation I found in the 
web EXIT exits the command.com in Win9x (like without the /b switch in 
Win2k+).

There is another way which will work on Win9x too ... but it is more a 
hack :

Example:

ECHO %ERRORLEVEL% | CHOICE /C:12345678 /N >NUL

Will set the errorlevel 1-8. But it won't work with negative error 
levels or errorlevels greater or equal than 10. I don't know another 
way, sorry :/

Regards
Mike
