A certain processor supports only the immediate and the direct addressing modes. Which of the following programming language features cannot be implemented on this processor?

Faster access to non-local variables is achieved using an array of pointers to activation records called a

Given the following Pascal like program segment:

Procedure A;

     x,y:intger;

     Procedure B;

            x,z:real;

            S1

     end B;

     Procedure C;

            i:integer;

            S2;

     end C;

end A;

The variables accessible in S1 and S2 are

The correct matching for the following pairs is

List - I
(A) Activation record
(B) Location counter
(C) Reference counts
(D) Address relocation

List - II
(1) Linking loader
(2) Garbage collection
(3) Subroutine call
(4) Assembler
