The use of the high level language made each programmer a factor of 5 to 10 more productive in a coding sense and more concerned with the semantics than the syntax of modules.
All our work, our whole life is a matter of semantics, because words are the tools with which we work, the material out of which laws are made, out of which the Constitution was written. Everything depends on our understanding of them.felix frankfurter
Visual modeling is a usage of images in various business-fields (in the industry, science, management etc.). There are additional limitations on these images distinguishing them from arbitrary pictures - they are created from the standard “patterns” having defined semantics and way of usage.
Von Neumann languages do not have useful properties for reasoning about programs. Axiomatic and denotational semantics are precise tools for describing and understanding conventional programs, but they only talk about them and cannot alter their ungainly properties. Unlike von Neumann languages, the language of ordinary algebra is suitable both for stating its laws and for transforming an equation into its solution, all within the "language."john backus
The establishment of formal standards for proofs about programs [...] and the proposal that the semantics of a programming language may be defined independently of all processors for that language, by establishing standards of rigor for proofs about programs in the language, appears to be novel.robert w floyd
For having a clear influence on methodologies for the creation of efficient and reliable software, and for helping to found the following important subfields of computer science: the theory of parsing, the semantics of programming languages, automatic program verification, automatic program synthesis, and analysis of algorithms.robert w floyd
C is not clean – the language has many gotchas and traps, and although its semantics are simple in some sense, it is not any cleaner than the assembly-language design it is based on.erik naggum
From semantics to shipbuilding, from dream theory to propositional logic, any specialist … is invariably astonished to discover that modern knowledge was foreshadowed at the time. … Should we not replace these foreshadowings by the study of the influences of Hellenistic thought on modern thought?lucio russo
I suppose one could claim that an undocumented feature has no semantics. :;:-(larry wall
Today some evidence arises that UML will more and more be used not as a specification language but as a high level programming language. This has some advantages, as if the concepts of UML are executable, they can immediately be animated and tested, or the generated code even be used as implementation. Thus UML probably will have an implementation-oriented semantics describing this animation.
Executable UML (xUML) consists of UML class diagrams, UML state machines and an action language which complies with the UML action semantics. There are several action languages in use; we refer to for a somewhat limited overview. The xUML models to be translated are expressed in the Cassandra/xUML dialect, as developed by KnowGravity.
