RE: conditioning indicator on an ENDDO

Of course the way to fix that is to do this:

  While  NOT %EOF(mafileL6)
    ReadE  Tk421 MaFileL6;
    // do whatever here... 
    OnEvent   %EOF(maFileL6)
    Leave;
  Enddo;

The "ON" clause of the WHILE sets up an condition similar to the MONITOR
opcode. When the condition occurs,t he code inside the OnEvent opcode is
performed; hence the loop is exited. 
Okay, so this is just more of my wishful thinking, Hans. :)

Hans,

I did look it up, but in the RPGLE manual.  I figured the rules would be
the same, so I didn't think to look in the rpg400 manual.

all it said (and I looked at both conditioning indicators and end(XX)
sections) was that conditioning indicators were optional for enddo, but not
valid for any other.

Thanks to all for confirming my suspicions

btw, I would have done it this way, but then i've never been accused to my
face of being 'enlightened' ;)

reade TKMANO MAFILEL6;

dow not %eof(mafilel6) and MASTS <> 'A';
  reade TKMANO MAFILEL6;
enddo;

I hope this starts another semi-monthly 'dow with priming read or dou'
arguement!!!
<ducking>

I for one had to look it up in the Reference manual. Yes, the loop exits
when *IN40 is on. I suppose these days more enlightened RPG programmers
would code that as:

      DOW MASTS <> 'A';
          READE TKMANO MAFILEL6
          IF %EOF(MAFILEL6);
              LEAVE;
          ENDIF;
      ENDDO;

Cheers! Hans
