Embedding language

There are many reasons for this choice, among them the prior existence of control structures, data structures, input/output facilities, and a general von Neumann framework. Further, a preprocessor can be implemented to compile Multilin into the embedding language and a selection of subroutine calls which can be coded specifically for each architecture. 

PL/I has its problems, both theoretical (16) and practical (limited availability), but its structure and wealth of primitives make it highly desirable. I have therefore chosen PL/I as the embedding language of Multilin. Much of Multilin s syntax is therefore inherited from PL/I. The major extensions are the addition of new attributes and keywords, and the introduction of a summation convention along with an extension of the meanings of certain PL/I operators. 

There are several major advantages in creating an embedded language with... 

When a new language is created, it is obviously necessary to ensure that the semantics of the language are well defined. Less obvious, perhaps, is that this is true also for embedded languages it is extremely important to define exactly which parts of the original language are part of the new language, and what extensions are introduced. Failure to do so results in ambiguities, which lead to interpretation errors and descriptions that cannot be carried between tools. 

Using a chemistry-aware embedded language like Scientific Vector Language (SVL), the Molecular Operating Environment (MOE) engine is not dependent on hardware and operating system [21], More than 80 MOE nodes are included, for example, node for retrosynthetic accessibility, protonation, Murcko framework generation. Shannon entropy model creation, InChl calculation, pharmacophore... 

On a larger scale, self-contained application programs can be driven by each other object linking and embedding/Component Object Model (OLE/COM), UNIX pipes and signals, and Apple events allow this to happen. Communicating components can be written in different languages, and each can execute in its own space. 

Morphisms are related to faithful maps, which lead naturally to the notion of a faithfully embedded closed subset. Such subsets provide an appropriate language for an attempt to establish so-called recognition theorems. These theorems deal with the question of which schemes are quotient schemes of thin schemes. We shall come back to recognition theorems and their role in scheme theory later in this preface. 

Encapsulated PostScript, or EPS. PostScript is a programming language developed by Adobe to describe pages, graphics, and fonts an EPS file is coded to be embedded in a large PostScript file. 

Implementation. As alluded to earlier, the features of Multilin are embedded into an existing language. (Rephrasing, Multilin is defined as an extension of an existing language.)... 

Although the knowledge required to assess the potential for the prevention or dissipation of hazards is often held by different abstractions of the overall representation, the semantic relationships of the modeling languages afford efficient access to this information. The effect of protective processes, equipment restraints, sensors and control systems, emergency procedures, etc., are captured as constraints. Constraints may be embedded in the underlying representation as equations, or be associated directly to it via a constraint list, i.e., a collection of explicit process restraints. These restraints may be passive, such as materials of construction, or... 

In writing this book I have benefited greatly from those who have ventured this road before me and produced great published works. I have tried to acknowledge them in the bibliographies however, it is impossible for me to fully credit these authors and quote their written works for they may be embedded in the very language of preformulation sciences. However, despite much care, it is inevitable that errors remain these are aU mine and I would appreciate it if the reader would bring them to my attention at niazi niazi.com so that I may correct them in the future editions of the book. 

CLIPS program code can be embedded within procedural code written in C, Java, Fortran, and ADA and provides a series of protocols for integration with software written in other programming languages. Although CLIPS is written in C, it can be installed on different operating systems, like Windows 95/98/NT/2000/XP, MacOS X, and UNIX, without code changes. It can be ported to systems with ANSI-compliant C or C-H- compilers.
