I can't believe this discussion has gone on so long.
(And I can't believe I'm responding!)

Add this snippet of V4R2 code and tell me what's more
readable:

     C                  CHAIN     rcd
     C                  IF        NOT %FOUND
     C                  LEAVE
     C                  ENDIF

Fact is, the traditional indicators are becoming a
thing of the past.  As of V4R2, there are very few
cases where an old-style indicator is still needed.
Eventually, we'd like to make it even easier to
avoid them entirely, using techniques that do not
require compromising readability.

Cheers!  Hans
