the static-chain method could be expanded slightly by using two static links in each activation record instance where the second points to the static grandparent activation record instances. how would this approach affect the time required for subprogram linkage and nonlocal references?

The Static Chain Method In static-scoped languages with nested subprograms, static chains are the principal technique of implementing accesses to non-local variables. A static chain is a collection of static links that connects different activation record instances.What is a static chain?A static chain is a collection of static links that connects different activation record instances in the stack. The static link, static scope pointer, in an activation record instance for subprogram A points to one of A's static parent's activation record instances.Estimating the costs of nonlocal references is challenging for a programmer working on a time-critical application since the cost of each reference relies on the depth of nesting between the reference and the scope of declaration.The stack with static links is as follows: Actual access to non-locals begins with the static link, because it is the callee's static parent, but if there are references to non-locals outside this scope, they must be searched.The Static Chain Method In static-scoped languages with nested subprograms, static chains are the principal technique of implementing accesses to non-local variables.
