 Both ITER and LEAVE are effectively GOTOs, so your last statement, while
technically accurate, is inaccurate in spirit.

 A "GOTO the end of a SR" can make the code *much* clearer and eliminate a
potential source of bugs.  When the logic is complex, it's very clear to
say: "If this condition is true, we're outta here" as opposed to seeding
the loop counter w/ *HIVAL and putting extra conditioning statements along
the way to make sure extra code doesn't get executed.  

 This is not a purist veiw, just a practical one.
