Why iter??  A leave would be more clear in this case....

[Marvin Radding:] I have been using iter for a few years now.
[Marvin Radding:]
Here is my code:

/free

  Setll myfile;

  Dou %eof(myfile);
    Read myfile;
    If %eof(myfile);
      Iter;
    Endif;

// other processing

  Enddo;

/end-free

One thing I like about this paradigm, when I decide I want to skip this
record a simple 'iter' will get me the next record.  Simple and easy to
understand code.

Marvin

Since I've developed a fondness for iter I'd like to do something like
...
setll(e) MyFile Mykey;
dou %status(reade(e) MyFile MyKey)<>0;
  // process
  ...
  iter;
  else;
  ...
EndDo;

I take it the way to do this is to make a one statement subprocedure
that does the reade and make the code look like

setll(e) MyFile Mykey;
dou ReadLoopProc<>0;
  // process
  ...
  iter;
  else;
  ...
EndDo;

P ReadLoopProc   b
D ReadLoopProc   PI   like(returnvar)
D  returnvar      s            5i 0
/free
 reade(e) MyFile MyKey;
 returnvar=%status(MyFile);
 return returnvar;
/end-free
P ReadLoopProc  E
