What is printed by the print statements in the program P1 assuming call by reference parameter passing?

Program P1()
{
     x=10;
     y=3;
     func1(y,x,x);
     print x;
     print y;
}
func1(x,y,z)
{
     y=y+4;
     z=x+y+z;
}

Consider the following program

Program P2
      var n:int;
      procedure W(var x:int)
      begin
          x=x+1;
          print x;
      end

      procedure D
      begin
          var n:int;
          n=3;
          W(n);
      end
begin     \\begin P2
      n = 10;
      D;
end

If the language has dynamic scooping and parameters are passed by reference, what will be printed by the program?

Given the programming constructs:

(i) assignment
(ii) for loops where the loop parameter cannot be changed within the loop
(iii) if-then-else
(iv) forward go to
(v) arbitrary go to
(vi) non-recursive procedure call
(vii) recursive procedure/function call
(viii) repeat loop,

which constructs will you not include in a programming language such that it should be possible to program the terminates (i.e., halting) function in the same programming language.

Consider the following program in a language that has dynamic scooping:

var x: real;
procedure show;
         begin print(x); end;
procedure small;
         var x: real;
             begin x: = 0.125; show; end;
begin x:=0.25;
         show; small
         end;

Then the output of the program is:
