See the section about "labelled headers". if, switch, while, for and loop all may have a label into the header, which some control flow instructions can use.

Like in

while 1 label "top_ loop" do 
  -- something 
  for idx = 1 to whatever do 
    if something_happened() then 
      exit "top loop" -- this gets out of the while loop with that label 
                      -- you could also say exit 2 or exit 0, but they are less easy to maintain. 
                      -- you cannot use anything variable here 
    end if 
  end for 
end while
