RE: Is Iter passe'?

Some programmers use DOW and some like to use DOU.  Example is below:
==========================================================================
C     PROKEY        SETLL     FRP003
C                   DOU       NOT %EQUAL(FRP003)
C     PROKEY        READE     FRP003
C                   IF        %EOF(FRP003)
C                   LEAVE
C                   ENDIF
*
C                   IF        FCCOD = 'DT'
C                   EVAL      ARRIVEDT = FCDAT
C                   EVAL      ARRIVETM = FCTIM
C                   ENDIF
*
C                   ENDDO
=================================================================

I suspect the original programmer was trying to avoid using a priming read
before the do loop?   Today we'd setll, read, and dow not %eof I believe,
with the next read being just before the enddo..

The "Iter" operation definitely isn't passé, what you ought to be trying

to remove is the use of the conditioning indicators instead

Hello, I was looking at a programmers code. They have things like

   dou *in99

read filex                 99

           99  Iter



How do you remove the use of iter these days?
