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:
“Sunshine of late afternoon—
On the glass tray
a glass pitcher, the tumbler
turned down, by which
a key is lying—And the
immaculate white bed”
—William Carlos Williams (1883–1963)
“The power of a text is different when it is read from when it is copied out.... Only the copied text thus commands the soul of him who is occupied with it, whereas the mere reader never discovers the new aspects of his inner self that are opened by the text, that road cut through the interior jungle forever closing behind it: because the reader follows the movement of his mind in the free flight of day-dreaming, whereas the copier submits it to command.”
—Walter Benjamin (1892–1940)
