Each object in the database has an ID number which appears after
the name of an object, and is followed by any flags on the object.

For example, foo(#3672PM)
is a Player, Male, named foo, and has object number #3672.

This object number is the database reference number (sometimes
called a "dbref"), and is used to specify objects at a distance;
i.e. @link <exit>=#<room ID number>. You will only see the ID number
of objects you own, or which are set LINK_OK, ABODE, or UNWANTED.
Gods can see the numbers and flags on all objects.
Wizards can see the numbers and flags on all non-Quelled objects.
