Note(s) Attention is drawn to the notes (particularly the definition of the term "variable") on page 1 of these elaborations. In this class: The term "data" is understood to be synonymous with "information", and the term "information" is therefore not used in sub-class Fulltext... Hierarchy... Expanded...G06C or Fulltext... Hierarchy... Expanded...G06F. The terms "calculating" and "computing" are both understood to include, inter alia, operations on numerical values and on data expressed in numerical form; of these words "computing" is used throughout the class. "Computation" is derived from this interpretation of "computing". In the French language the word "calcul" will serve for either word. In those sub-classes which include simulators: a simulator in class Fulltext... Hierarchy... Expanded...G06 is concerned with the mathematics of computing the existing or anticipated conditions within the real device or system; control functions derived from simulators are not in class Fulltext... Hierarchy... Expanded...G06 but are generally in class Fulltext... Hierarchy... Expanded...G05, although they may be in the sub-class for the device controlled; measurement of an individual variable to serve as an input to a simulator is in class Fulltext... Hierarchy... Expanded...G01; a simulator is regarded as a teaching or training device proper to class Fulltext... Hierarchy... Expanded...G09 if the simulator gives perceptible sensations having a likeness to the sensations the student would experience in reality in response to actions taken by him. Simulators which demonstrate, by means involving computing, the functioning of apparatus or of a system are in class Fulltext... Hierarchy... Expanded...G06, if no provision exists elsewhere. Components of simulators, if identical with real devices or machines, are classified in the relevant sub-class for these devices or machines and not in class Fulltext... Hierarchy... Expanded...G06 or Fulltext... Hierarchy... Expanded...G09; a simulator may use the same time scale as the real device or operate on an expanded or compressed time scale; models of real devices to reduced or expanded scales are not regarded as simulators. The term "record carrier" is understood to mean a body, such as a cylinder, disc, card, tape, or wire, capable of permanently holding information, which can be read-off by a sensing element movable relative to the recorded information.
