How to set errorlevel ?

[Ed Dyreen]

'
currently I use this overflow technique to set the errorlevel, I wonder whether it can be shortened:

Code: Select all

>nul 2>&1 ( if !$error! neq 0 ( set /a $? = 0 ) else set /a $? = 9999999999 )

It can only switch the errorlevel between 1 and 0, I wonder if it's possible to change that, like u can do at the end of a function

Code: Select all

exit /b 1001

I use it for chaining macro's:

Code: Select all

>nul 2>&1 ( if !$error! neq 0 ( set /a $? = 0 ) else set /a $? = 9999999999 ) &&echo.yes ||echo.no !errorlevel!

Try

Code: Select all

cmd /c exit 5
echo %errorlevel%

isn't that like very slow ?, it's definetly short, I think I'll take it

It takes some time to load another instance of cmd.exe. How fast it is depends on your machine.
