2. Guarded Command Language - Wikipedia

   en.wikipedia.org/wiki/Guarded_Command_Language

   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 ...

3. Conditional (computer programming) - Wikipedia

   en.wikipedia.org/wiki/Conditional_(computer...

   The Guarded Command Language (GCL) of Edsger Dijkstra supports conditional execution as a list of commands consisting of a Boolean-valued guard (corresponding to a condition) and its corresponding statement. In GCL, exactly one of the statements whose guards is true is evaluated, but which one is arbitrary.

4. Predicate transformer semantics - Wikipedia

   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.

   en.wikipedia.org/wiki/Occam_(programming_language)

   ALT specifies a list of guarded commands. The guards are a combination of a Boolean condition and an input expression, both optional. Each guard for which the condition is true and the input channel is ready is successful. One of the successful alternatives is selected for execution. Example:
