An odd structure (?)

RE:     An odd structure (?)

CORRECTION:
 " With example 2 you have to actually read right to left,"

Should have been,  "With example 1....."

Sorry

--- example 1 -----------------

CHAIN  FILE( Customer )   KEY( Id )  NR( CustomerNotFound )
IF     CustomerNotFound
         MOVE  'This Customer does not exist'  TO  ScreenErrorMsg
ENDIF

---- example 2 --------------------------------   
        
        ID      CHAIN   CUSTF                            54
        *IN54   IFEQ    *ON
                MOVE    ERR,1          SCRERR
                ENDIF
----------------------------------


With example 2 you have to actually read right to left, pass each piece
of data to the main processor(brain) who does a translation/lookup to 
see if it's what it's looking for.  It must first understand it, then 
decide.  

With columnar,  there is no right to left reading/translating done.
the eyes do most of the work
At least that is what I found.
But I'm probably wrong again.
