But, unlike a 'force' where the value is retained until a subsequent 'release' is used, or a continuous assignment, where a value is continuously assigned to a wire, this assignment is for one-time only. This is equivalent to a procedural assignment to a register type variable. Wires are read-only variables. black snakes found in georgia
