Just to make life fun, some/most UK cookers separate the grill from the oven. The grill will traditionally have a drop down door and several shelving levels very close together, that door is left open when the grill is in use. It can be at the very top of the cooker or immediately above the oven. The oven will have a swing door and obviously closed when in use. That's assuming the cooker is a free standing cooker.
These are what I grew up with an what my inlaws still have.

In this one, the grill is the first door down... it also acts as a warning drawer.
The more modern versions put the grill between the oven and the rings for safety reasons!

Life only started to combine them when they started with built-in ovens such as I have now.
Even my last tenancy place here in Aus had a free standing gas oven with grill at the top.
