The Guarded Command Language (GCL) is a programming language defined by Edsger Dijkstra for predicate transformer semantics in EWD472. [1] It combines programming concepts in a compact way. It makes it easier to develop a program and its proof hand-in-hand, with the proof ideas leading the way; moreover, parts of a program can actually be ...
Predicate transformer semantics were introduced by Edsger Dijkstra in his seminal paper "Guarded commands, nondeterminacy and formal derivation of programs".They define the semantics of an imperative programming paradigm by assigning to each statement in this language a corresponding predicate transformer: a total function between two predicates on the state space of the statement.
Guards are the fundamental concept in Guarded Command Language, a language in formal methods. Guards can be used to augment pattern matching with the possibility to skip a pattern even if the structure matches. Boolean expressions in conditional statements usually also fit this definition of a guard although they are called conditions.

The Oxford English Dictionary defines a "gazetteer" as a "geographical index or dictionary". [6] It includes as an example a work by the British historian Laurence Echard (d. 1730) in 1693 that bore the title "The Gazetteer's: or Newsman's Interpreter: Being a Geographical Index". [6]
Military outposts, most recently referred to as combat outposts (COPs), served as a cornerstone of counterinsurgency doctrine in Iraq and Afghanistan.These permanent or semi-permanent structures, often located in or near populated areas, enabled military forces to secure key lines of communication or infrastructure, secure and co-opt the populace, assist the government in restoring essential ...
