I have the following code in a gateway tag change script: if event.newValue ==0: system.net.openURL(“file://D:\ISD files\Normal mode.bat”) else: system.net.openURL(“file://D:\ISD files\Backup mode.bat”) When the script runs I get an error in the console something about not having the attribute “openURL”. Sorry I forgot to write down the exact error. When I try the openURL statement in a client tag change script or the script playground it works just fine (except the file can’t be found because it exists on the gateway). ---

You can’t call the openURL function on the gateway since the function opens a web browser. It is meant for the client machine. What you want to use is system.util.execute:`if newValue.value == 0: system.util.execute(["D:\\ISD files\\Normal mode.bat"]) else: system.util.execute(["D:\\ISD files\\Backup mode.bat"])` ---

I figured it had to be something like that. Thank you. ---

I am getting a syntax error for that system.util.execute command string. ---

“” is an escape character in Python. You need to use “\” to get a literal backslash.`system.util.execute(["D:\\ISD files\\Normal mode.bat"])` ---

I thought of that as well but it fails with the “\” as well. It appears the compiler automatically changes the “” to “\” anyway. I attached a screen shot of the syntax error. ![](https://us1.discourse-cdn.com/inductiveautomation/original/1X/d2be9e1300c79a3a88cc088cd3dbdeade99ebd47.png) ---

It looks like you are using spaces and a tab instead of two tabs on line 3 (and probably line 5 as well). If you remove all whitespace and replace it with tabs, it will work. ---

That was it. It must have something to do with the copy and paste from the code in the post. Thanks for your help. ---

For reference, you can also use r"D:\ISD files\Normal mode.bat". The r refers to regex string literal and will not use the backslash escape. Only catch is that the last character cannot be a backslash (i.e r"D:\ISD files"). I didn’t verify this with jython so I could still be wrong but this is standard python behavior.
