A display list, also called a command list in Direct3D 12 and a command buffer in Vulkan, is a series of graphics commands so that they may be later run when the list is executed. [1] Systems that make use of display list functionality are called retained mode systems, while systems that do not are as opposed to immediate mode systems.
Standard environment variables or reserved environment variables include: %APPEND% (supported since DOS 3.3) This variable contains a semicolon-delimited list of directories in which to search for files.

Local variables may have a lexical or dynamic scope, though lexical (static) scoping is far more common.In lexical scoping (or lexical scope; also called static scoping or static scope), if a variable name's scope is a certain block, then its scope is the program text of the block definition: within that block's text, the variable name exists, and is bound to the variable's value, but outside ...
Variable binding relates three things: a variable v, a location a for that variable in an expression and a non-leaf node n of the form Q(v, P). Note: we define a location in an expression as a leaf node in the syntax tree. Variable binding occurs when that location is below the node n. In the lambda calculus, x is a bound variable in the term M ...
Variables are denoted by a string consisting of letters, numbers and underscore characters, and beginning with an upper-case letter or underscore. Variables closely resemble variables in logic in that they are placeholders for arbitrary terms. A variable can become instantiated (bound to equal a specific term) via unification.
The state variable for an inductor is the current through the inductor, while that for a capacitor is the voltage across the capacitor. In ecosystem models , population sizes (or concentrations) of plants, animals and resources (nutrients, organic material) are typical state variables.
