Scripting question

I am trying to run a simple script in an environment that has both Windows
Vista and Windows 2000:

----- script below -----
if %os_version% == 5.0.2195 goto W2k

:Vista
echo "Windows Vista"
got End

:W2k
echo "Windows 2000"

:End
----- end script -----

This runs fine on Windows 2000, but in Vista I get the error "goto was
unexpected at this time"

If I remove the %%, then the script runs, although it never evaluates
properly. I guess the question is how can I run this script on both OSes so
it evaluates properly?

Thanks,
Marc

Since by default Vista (and XP for that matter) do not have an
environment variable called OS_VERSION, unless you are setting it
yourself the statement 'if %os_version% == 5.0.2195 goto W2k' evaluates
to 'if == 5.0.2195 goto W2k', which is an incomplete statement and
causes your error. The fix is easy - enclose both sides of the
expression in quotes like this (and incidentally, remove the spaces
around the == which can also cause problems):

if "%os_version%"=="5.0.2195" goto W2k

That way, a blank OS_VERSION causes the statement to evaluate to 'if
""=="5.0.2195" goto W2k', which won't cause the error.
