System Global Variables

Is there a way to get a list of system global variables? I’m looking specifically for ip_user so I can capture the users ip address in my application.

Thanks but I know that method. SC has an ip_user variable it uses for logging. Need to know how to get that.

I really can’t understand why SC doesn’t have a document with all of the available System Global Variables and their definitions. This is not rocket science to create it.
