For geezers like me who know that an indicator is a BOOL variable 
with a number instead of a name, the lack of clarity comes from not 
knowing what bit of code set each indicator on or off: the example 
was carefully crafted to completely obliterate any means of 
understanding the code (which was the point, IIRC!)

Even the subroutine name is disguised.

People have railed against the use of indicators for *EVER because 
the indicator number does not help understanding the intent of the 
code.  Without researching the rest of the program, we'll never 
understand this line of code.  Us geezers have to learn to write more 
like:

     C           AMT$      IFGT WARN$
     C           CUSTCD    ANDLTBESTCD
     C           REGION    ANDEQMIDWST
     C                     EXSR WARN
     C                     ENDIF

which isn't crystal clear without comments, but it's _better_
I'm personally happy that there are RPGers among us who don't use 
left hand indicators, because it means that they're using more 
meaningful names instead!
