			* Create is a synonym for Allocate. It causes storage to be allocated for a based variable. A file or set where the data is to be allocated may be specified.
			* Delete is a synonym for Free. Delete frees a based variable and optionally removes it from all sets of which it is a member.
			* Find locates an entity that is a member of a set or container based on specified conditions. An optional <code>ELSE</code> clause is executed if no entities are found.
			* For Each heads a group of statements to be executed for all entities or sets matching a specified condition.
			* Insert inserts an entity into a specified set. Optionally, the placement of the new entity relative to other elements of the set may be specified.
			* Let sets a locator variable to reference a specified set.
			* Remove removes an entity from a set.
