You are looking at a command called setzone

synopsis:
setzone {object} as {zonename}
or
setzone {zonename} (to change the location's zone)

If there is no zone set, and the object is unlocked (or was locked by you):

- add's the zone material.
- sets the zonename into the zone materials value.

If there was a zone already set:

- tells you the current zone name and doesn't change it.

But if you do it nicely:
- tells you the current zone name (if such exists) and changes it anyway.
