- abstract interpretation — (theory) A partial execution of a program which gains information about its semantics (e.g. control structure, flow of information) without performing all the calculations. Abstract interpretation is typically used by compilers to analyse programs in order to decide whether certain optimisations or transformations are applicable. The objects manipulated by the program (typically values and functions) are represented by points in some domain. Each abstract domain point represents some set of real ("concrete") values. For example, we may take the abstract points "+", "0" and "-" to represent positive, zero and negative numbers and then define an abstract version of the multiplication operator, *#, which operates on abstract values: *# | + 0 - ---|------ + | + 0 - 0 | 0 0 0 - | - 0 + An interpretation is "safe" if the result of the abstract operation is a safe approximation to the abstraction of the concrete result. The meaning of "a safe approximation" depends on how we are using the results of the analysis. If, in our example, we assume that smaller values are safer then the "safety condition" for our interpretation (#) is a# *# b# <= (a * b)# where a# is the abstract version of a etc. In general an interpretation is characterised by the domains used to represent the basic types and the abstract values it assigns to constants (where the constants of a language include primitive functions such as *). The interpretation of constructed types (such as user defined functions, sum types and product types) and expressions can be derived systematically from these basic domains and values. A common use of abstract interpretation is strictness analysis. See also standard interpretation.

- encapsulated postscript — (EPS) An extension of the PostScript graphics file format developed by Adobe Systems. EPS is used for PostScript graphics files that are to be incorporated into other documents. An EPS file includes pragmas (special PostScript comments) giving information such as the bounding box, page number and fonts used.

- graphical kernel system — (graphics, standard) (GKS) The widely recognised standard ANSI X3.124 for graphical input/output. GKS is worked on by the ISO/IEC group JTC1/SC24. It provides applications programmers with standard methods of creating, manipulating, and displaying or printing computer graphics on different types of computer graphics output devices. It provides an abstraction to save programmers from dealing with the detailed capabilities and interfaces of specific hardware. GKS defines a basic two-dimensional graphics system with: uniform input and output primitives; a uniform interface to and from a GKS metafile for storing and transferring graphics information. It supports a wide range of graphics output devices including such as printers, plotters, vector graphics devices, storage tubes, refresh displays, raster displays, and microfilm recorders.
