Summing up??

(1) compiles to (2)       ,runs into (2) "Executed STOP process"
(3) compiles to (Appendix),runs into (4) "All IF branches failed"
(5) compiles to (Appendix),runs into (6) "Executed STOP process"
(7) compiles to  much,     runs into (8) "Terminating application"

Q1. And you are saying they are ALL the same ?-)
Q2. What's the purpose of saying that they are formally the 
    same if they aren't practically the same?
Q3. How will KRoC behave?

You don't have to answer this, as an engineer I pretty much
_feel_ the answer. And besides, all "runs into" are just fine
with me, they all stop me one way or the other!

PS. I know you haven't been even mentioning (5), but I 
    formally uncorrectly assumed that's what Peter first meant:-)

  (1) STOP
  (2) SETERR(MSG_STOP);

  (3) IF           
        FALSE
          SKIP
  (4) SETERR(MSG_IF);
  
  (5) IF
        TRUE
          STOP
  (6) SETERR(MSG_STOP);
  
  (7) CHAN OF INT a, b:  
      PAR
        SEQ
          a ! 42
          b ! 99
        INT x, y:
        SEQ
          b ? x
          a ? y
  (8) SETERR (MSG_TA); 
      "Terminating application" (SPOC) 
      "Erroneous channel usage" (Peter/Denis)
