Setting and using an environment variable in the same command

I am using Windows 7 and I want to set up an environment variable and use it in the same command. Specifically, I want to execute the following 2 commands simultaneously as a single command-:

set MYPATH="C:\Program Files (x86)\Microsoft Visual Studio 11.0"

In other words, I want the Windows version of this. This is what I've tried so far -:

set MYPATH="C:\Program Files (x86)\Microsoft Visual Studio 11.0" && cmd.exe /C "%MYPATH%\VC\vcvarsall.bat"

But it isn't working. So, Is there any way of doing this in Windows ?


This can be done by writing -:

cmd.exe /X /V:ON /C "set MYPATH="C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\varsall.bat" && !MYPATH!"
