You can call "push_mark" twice in the first step.  However, I would
use one of the narrow functions (narrow, or narrow_to_region):

  1.  push_mark ()
  2.  Move cursor to define a region
  3.  narrow_to_region ();
  4.  Operate on region, e.g.,
    
         bob ();  % Goto top of narrowed region
	 do 
	   {
	      insert ("    ");  % shift line to right
	   }
	 while (down (1));      % goto next line

	 % Do something else
	 bob ();
	 do 
	   {
	      do_something_else_to_line ();
	   }
	 while (down (1));      % goto next line
	 
	 % Replace all occurrences of foo in region with bar
	 bob ();
	 replace ("foo", "bar");
	 
  5.  widen_region ();
