Do I have enough information to do this problem and What exactly are the static and dynamic Chains? I am not a programmer and I am trying to get this right.

Show the stack with all activation record instances, including static and dynamic chains, when executions reaches position 1 in the following skeletal program. Assume Bigsub is at level 1.

procedure Bigsub is
procedure A
procedure B is
begin -- of B
... <-- 1
end; -- of B
procedure C is
begin - of C
...
B;
...
end; -- of C
begin - of A
...
C;
...
end; -- of A
begin -- of Bigsum
...
A;
...
End; -- of Bigsum
