Data
Nominal
Aliases None.
Information This is about the elementary nominals.

The only nominals eligible to be in this are those having a specific implementation to improve efficiency. This is mainly done by taking advantage of the zero testing instructions of the microprocessors.  For , the Boolean type is a nominal element for 0 to be the representation of false. This policy is therefore applicable to nominals used extensively in ISA and having one of their values used much more than the others.

Note kind
Information The nominal giving the list of note type on Metaclasses.
Literal
Explanation The motivation behind of the Metaclass.
It explains why the element is like this.
Typical usage: Software developer private documentation.
Injunction The way to use the Metaclass.
It describes how to use the element.
Typical usage: Software user documentation like online help.
Persuasion The flag of this Metaclass.
It defines when and where to use the element.
Typical usage: Software user suggestion like tooltip.
Note kind
Position
Information A Position is a particular location where an occurrence stands in an ordered set.

When the occurrence matches several positions, the precedence order is:  First, Last, Middle, Second, Penultimate, Other.

On sets having an even number of elements N, the Middle position maps to the index I as: I = N/2.
Position
