Windows Batch File

Experts,
I need some assistance in creating a Windows batch file that needs to run on startup:

I have an environment variable called EWF which will be set to either 0 or 1; I need the batch file to query the environment variable and perform some actions if it's a 0 or do nothing if it is a 1.

Any help?

This line will leave the batch script immediately if EWF is 1, and continue otherwise:
if "%EWF%"=="1" goto :eof
echo EWF is 0

Open in new window

Or you can do something like this:
if "%EWF%"=="0" (
	echo EWF is 0
)

Open in new window
