I have (almost) never coded COBOL, so I have trouble wrapping my head around:
SMOD (IND1) = 'B' OR 'R'
Does it mean:
( SMOD (IND1) = 'B' ) OR 'R' or
SMOD (IND1) = ( 'B' OR 'R' ) or (implied Distributive Law):
SMOD (IND1) = 'B' OR SMOD (IND1) = 'R'
I'd have even more trouble with:
SMOD (IND1) NOT = 'B' OR 'R'
SMOD (IND1) NOT = 'B' OR SMOD (IND1) NOT = 'R'
... which seems to be a verbose expression for TRUE. I've
seen programmers fall into that trap.
