Installing the account objects in the global namespace
The bank account and stock account objects are prototypes; we can make new
accounts by copying them. The most common way to make a prototype well-
known is to install it in the global namespace.
The global namespace is implemented by an object which is reached by the globals
slot in the lobby. Globals is a parent slot, so anything that inherits from the lobby
also inherits all the slots in globals. In Self 4.0, there are 313 slots in this
object.
Categories organize slots
To organize the slots in an object, each slot can be in a category. Categories can
themselves be categorized, forming a hierarchy. The category name can be
anything - it serves no purpose other than documentation. New categories can be
added using the `Add category' item on the middle-button menu. A category
name can be edited by double-clicking on it. Slots can be moved between
categories in the same way that they can be moved between objects.
