Vista - Return value from VBScript to cmd file

I'm modifying a Windows command script that needs to use a value from the
Win32_OperatingSystem class. How can I call a VBScript from inside the cmd
script and return a value to the cmd script?

news:%23w0kMEVRJHA.4916@xxxxxxYour command script (=batch file) could look like so
@echo off
{Your code}
cscript //nologo c:\Scripts\YourScript.vbs
echo Return code = %ErrorLevel%
{More of your own code}

Your VB Script could terminate like so:
wscript.quite 9

While I'm here let me note that this approach can use a variable, as
well, but that it can only return an integer between 0 and 255 to a
batch procedure. For example, ...

nNumber = 2 + 2
wscript.quit nNumber

If the result is/can be larger than 255, is real or a string then try
something like this instead ...

in script:

Result = 123.456 ' for exaple
wscript.echo Result

then in batch ...

@echo off
:: {Your code}
for /f "delims=" %%a in ('cscript //nologo c:\Scripts
\YourScript.vbs') do (
set ScriptOut=%%a)
echo Script Result = %ScriptOut%

"Quite" so!

Thank you all. Your suggestions will save my day

Have you considered setting an environment variable in your script to the
value (string) that you want returned?

news:eIDF7lbRJHA.1448@xxxxxxHow exactly would you set an environmental variable in a script so that it
is available to the calling program?

>"Tom Lavedas" <tglbatch@xxxxxx> wrote in message<snip>Tom, One question. If the script returns multiple lines of output, your
example only catches the last line. How do I get it to capture the entire
output. I tried:

Set ScriptOut=
for /f "delims=" %%Z in ('cscript //nologo c:\cc_trigs\jvbsout.vbs') do (
Set BVBTemp=%%Z
Set ScriptOut=%ScriptOut%%BVBTemp%
)
echo Script output: %BVBTemp%

But this still just saves the last line.

its 'elegance' because of the 'hacks' needed to make it happen.

The reason it's not possible (within reason) is that a 'child' process
gets a *temporary COPY* of the environment. A script can modify this
COPY, but since it is temporary, it is NOT available to the calling
process once the script ends. Access to the non-volatile version of
the environment requires access to the Windows API, which cannot be
done easily in script. A supporting application could be called, but
all in all it seems much messier to me than the use of the FOR
statement.
