Forum Post: typeof variable that's set to NULL

Let's say we have this code:

[ ] ROSStateEnum ee = Normal
[ ] print(typeof(ee))
[ ] ee = NULL
[ ] print(typeof(ee))
[ ] exit

Second typeof crashes because ee is NULL. Is it somehow possible to get typeof variable that's set to NULL? Or maybe set ee to some default value (doesn't matter what if I can then get typeof)?

I've tried this:

ee = 1

but that also doesn't work. I don't know enum's type, so I can't cast 1 to the enum. Any suggestions would be appreciated. 

Thanks!
