The concept of "class" is closely related to the one of "object".  However, in BEE, the terms "class" and "object" are used interchangeably.  They both mean a "super variable" that holds multiple array variables (like a two-dimensional variable).

General Classes are used as common variables.  They are only accessible within the local context (e.g. inside the function they are defined) unless declared as "global" or "parent".

Variables that does not have a class part (class%) in their name belongs to the general class "value".  That is why "value%" is commonly omitted to increase readability.

When a General Class is used as an object (created by a constructor using the "new" syntax), it is called an Object Class.  The two do not have any semantic differences.
