Environment
Early video previews of the Subtext environment were released circa 2006, which demonstrated the semantics of Subtext programs, and the close integration with the Subtex environment and runtime.
Subtext programs are declared and manipulated (or mutated) by adding and linking elements of various types to a syntax tree, and entering in values or names as necessary, as opposed to typing out textual programs. Due to the design of the Subtext language and environment, there is no distinction between a program's representation and its execution. Like spreadsheets, Subtext programs are live executions within an environment and runtime, and programming is direct manipulation of these executions via a graphical environment. Unlike typical functional programming languages, Subtext has simple semantics and is easily applicable to reactive systems that require mutable state, I/O, and concurrency, under a model known as "Reactive Programming". Console input ("invocations") can be utilized via data flow within a Subtext program, allowing users to manipulate values interactively.

Famous quotes containing the word environment:
“The poorest children in a community now find the beneficent kindergarten open to them from the age of two-and-a-half to six years. Too young heretofore to be eligible to any public school, they have acquired in their babyhood the vicious tendencies of their own depraved neighborhoods; and to their environment at that tender age had been due the loss of decency and self-respect that no after example of education has been able to restore to them.”
—Virginia Thrall Smith (1836–1903)
“Today the young actors regard their environment with rage and disgust. They regard their Master not as disciples regard their Master, but as slaves regard their Master.”
—Judith Malina (b. 1926)
“We learn through experience and experiencing, and no one teaches anyone anything. This is as true for the infant moving from kicking to crawling to walking as it is for the scientist with his equations. If the environment permits it, anyone can learn whatever he chooses to learn; and if the individual permits it, the environment will teach him everything it has to teach.”
—Viola Spolin (b. 1911)
