RE: NOT on the left side

["Bob Cozzi \(RPGIV\)" <cozzi@xxxxxxxxx>]

The "N" data type in RPG IV is an indicator data type.
I can contain *ON or *OFF and can be tested like most other built-in
indicators.

C              IF          TOOBIG
C              do something when TOOBIG=*ON...
C              endif

Is the same code as:

C              IF          *IN38
C              do something when *IN38=*ON...
C              ENDIF

So rather than this:
     d TOBIG                              like(*inlr)

code this:

     d TOBIG                          1N
