Other Key Aspects
Action semantics embodies a level of abstraction that increases its comprehensibility. The specifics of the control and data flows that an action involves are implicitly incorporated in the action, as opposed to being explicitly expressed as the details of semantic functions are in denotational semantics. When an action is performed, most information processing and manipulation occurs automatically.
Program phrases are mapped to actions when constructing a definition of a programming language’s meaning in action semantics. The execution of a programming phrase corresponds to the performance of the action to which it maps.
The programming language specification generated from the application of action semantics can be broken down into a lower level (microsemantics) and an upper level (marcosemantics). The lower level consists of defining the meaning of action notation, while the upper level consists of defining the meaning of a programming language, using action notation to do so.

Famous quotes containing the words key and/or aspects:
“The key to the age may be this, or that, or the other, as the young orators describe; the key to all ages is—Imbecility: imbecility in the vast majority of men, at all times, and even in heroes, in all but certain eminent moments: victims of gravity, customs and fear. This gives force to the strong,—that the multitude have no habit of self-reliance or original action.”
—Ralph Waldo Emerson (1803–1882)
“That anger can be expressed through words and non-destructive activities; that promises are intended to be kept; that cleanliness and good eating habits are aspects of self-esteem; that compassion is an attribute to be prized—all these lessons are ones children can learn far more readily through the living example of their parents than they ever can through formal instruction.”
—Fred Rogers (20th century)
