nb_delete/1¶

"nb_delete(+ Name" )

` Delete the named global variable.

Global variables have been introduced by various Prolog
implementations recently. We follow the implementation of them in
SWI-Prolog, itself based on hProlog by Bart Demoen.

GNU-Prolog provides a rich set of global variables, including
arrays. Arrays can be implemented easily in YAP and SWI-Prolog using
 @ref functor_51 @"functor/3" and ` @ref setarg_51 @"setarg/3"` due to the unrestricted arity of
compound terms.
