title: Init build environment within a batch
body: <p>I'm using a windows batch file to run vxWorks build.
  In order to run the build, I need to run the wrenv.exe utility that set up the build environment.</p>
  
  <p>I'm trying the following, but the update operation fails</p>
  
  <blockquote>
    <p>call C:\WindRiver32\wrenv.exe -p vxworks-6.8<br>
    call wrws_update.bat -data "%WORKSPACE%" -l %APP_MODULE% -b build -c %CPU%</p>
  </blockquote>
  
  <p>How can I force the batch to "remember" the wrenv.exe settings?</p>
