To me it seems that the major problem with indicators is that their meaning is 
not self documenting. This is fine if the use of lefthand indicators is local to
the subroutine or function. If the value of the indicator is global in scope, 
you should assign the indicator value to a named variable.

C                       CHAIN   MSTFILE                      50
C                       eval              EOF_MSTFIL = *in50

Your point is well taken. The key part for me is that the test is close to 
the point of setting the indicator. I believe we all agree that maintaining 
RPGII stuff that set indicators in I-specs can be absolute murder.
     
I still welcome the move toward named indicators. And more freeform (like 
Buck's example-love it!). But one person's 'cleaner' is another person's 
'cryptic'. You pays your money and you takes your choice. In the end, we 
use our resective shop standards-oops, could be another thread unraveling 
here.
