Show the stack with all activation record instances, including static and
dynamic chains, when execution reaches position 1 in the following skeletal
program. Assume Bigsub is at level 1.
procedure Bigsub is
MySum : Float;
procedure A is
X : Integer;
procedure B(Sum : Float) is
Y, Z : Float;
begin -- of B
. . .
C(Z)
. . .
end; -- of B
begin -- of A
. . .
B(X);
. . .
end; -- of A
procedure C(Plums : Float) is
begin -- of C
. . . <1
end; -- of C
L : Float;
begin -- of Bigsub
. . .
A;
. . .
end; -- of Bigsub
