[Oberon] FJump and FixLink

[Andreas Pirklbauer]

  >  In short, I would have coded the procedures as follows:
  >
  >  PROCEDURE FixLink*(L: LONGINT);
  >    VAR L1: LONGINT;
  >  BEGIN
  >    WHILE L # 0 DO L1 := code[L] MOD 2000H; FixOne(L); L := L1 END
  >  END FixLink;
  >
  > PROCEDURE FixLinkWith(L0, dst: LONGINT); (* used for «UNTIL» *)
  >   VAR L1: LONGINT;
  >  BEGIN
  >    WHILE L0 # 0 DO
  >      L1 := code[L0] MOD 2000H; fix(L0, dst - L0 - 1); L0 := L1
  >    END
  >  END FixLinkWith;

PS: Which, if I am not mistaken, could also be expressed as:

   PROCEDURE FixLinkWith(L, dst: LONGINT);
     VAR L1: LONGINT;
   BEGIN
     WHILE L # 0 DO L1 := code[L] MOD 2000H; fix(L, dst-L-1); L := L1 END
   END FixLinkWith;

   PROCEDURE FixLink*(L: LONGINT);
   BEGIN FixLinkWith(L, pc)
   END FixLink;
