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.

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.
Two Iranian citizens are facing federal charges in connection to a drone strike that killed three US Army soldiers and injured dozens more in Jordan early this year, the US Justice Department ...
In computer programming, a guard is a Boolean expression that must evaluate to true if the execution of the program is to continue in the branch in question. Regardless of which programming language is used, a guard clause, guard code, or guard statement is a check of integrity preconditions used to avoid errors during execution.
The pair guarded each other for most of the game. Bueckers finished with 22 points. With the game tied at 67, Watkins passed the ball to Rayah Marshall for a layup with 1:21 left to give USC the lead.
