well I could do this easily with a routine but lets try this:

integer i i = 0
while x do  -- loop1
  ..some_code..
  while y do  -- loop 2
    if test_var then
      exit
    end if
    if want_out_of_loop_2 then
      i = 1
    end if
  end while  -- end of loop 2
  if i then
    exit
  end if
  ..more_code..
end while  -- end of loop 1
..target..

hope this helps,
Lewis Townsend
