com si rendono globali delle variabili d'ambiente in un file bat su win2k SENZA specificarle su sistema/variabili d'ambiente...?

dovrei rendere pubbliche le variabili env di ms vs.net per poter utilizzare cpan e compilare alcune cose...

esiste un modo o devo riempirle a mano??

le variabili vengono settate in "N:\Program Files\Microsoft Visual Studio .NET\Common7\Tools\vsvars32.bat"

@SET VSINSTALLDIR=C:\Program Files\Microsoft Visual Studio .NET\Common7\IDE
@SET VCINSTALLDIR=C:\Program Files\Microsoft Visual Studio .NET
@SET FrameworkDir=C:\WINNT\Microsoft.NET\Framework
@SET FrameworkVersion=v1.0.3705
@SET FrameworkSDKDir=C:\Program Files\Microsoft Visual Studio .NET\FrameworkSDK
@rem Root of Visual Studio common files.

@if "%VSINSTALLDIR%"=="" goto Usage
@if "%VCINSTALLDIR%"=="" set VCINSTALLDIR=%VSINSTALLDIR%

@rem
@rem Root of Visual Studio ide installed files.
@rem
@set DevEnvDir=%VSINSTALLDIR%

@rem
@rem Root of Visual C++ installed files.
@rem
@set MSVCDir=%VCINSTALLDIR%\VC7

@rem
@echo Setting environment for using Microsoft Visual Studio .NET tools.
@echo (If you also have Visual C++ 6.0 installed and wish to use its tools
@echo from the command line, run vcvars32.bat for Visual C++ 6.0.)
@rem

@REM %VCINSTALLDIR%\Common7\Tools dir is added only for real setup.

@set PATH=%DevEnvDir%;%MSVCDir%\BIN;%VCINSTALLDIR%\Comm on7\Tools;%VCINSTALLDIR%\Common7\Tools\bin\prerele ase;%VCINSTALLDIR%\Common7\Tools\bin;%FrameworkSDK Dir%\bin;%FrameworkDir%\%FrameworkVersion%;;%VJSHA RPTOOLS%;%PATH%;
@set INCLUDE=%MSVCDir%\ATLMFC\INCLUDE;%MSVCDir%\INCLUDE ;%MSVCDir%\PlatformSDK\include\prerelease;%MSVCDir %\PlatformSDK\include;%FrameworkSDKDir%\include;%I NCLUDE%
@set LIB=%MSVCDir%\ATLMFC\LIB;%MSVCDir%\LIB;%MSVCDir%\P latformSDK\lib\prerelease;%MSVCDir%\PlatformSDK\li b;%FrameworkSDKDir%\lib;%LIB%

@goto end

:Usage

@echo. VSINSTALLDIR variable is not set.
@echo.
@echo SYNTAX: %0

@goto end

:end

vorrei che questo bat partisse all'avvio (logon script) ma che settasse globalmente le var!
