RE: read on a do loop

People have heard me rant on why I stop using CLP.  Every time I go to use 
it (and we're on V5R3 in which CL got vastly improved), I run into a 
limitation that makes me hit a wall.
I find myself thinking the same way about if's versus select.
Every time I think I have a single case if I come up with 'the third 
option'.  I've pretty much made it another mantra to always use select 
instead of if.
1 - Nested if's are bug ugly.
2 - Using select makes you think about 'the third option'.

  If %eof(myfile);
    Leave;
  Endif;
  If Itactv = 'N';
    Iter;
  Endif;

becomes
  Select;
  When %eof(myfile);
    Leave;
  When %status(myfile)<>0;
    // some catastrophic file error occurred and needs to be handled.
  When Itactv='N';
    Iter;
  Other;
    // main body
    ...
  EndSl;

Granted, on a 'simple' if you'd only have
if x>y;
  // do this
EndIf;

Versus
Select;
When x>y;
  // Do this
Endsl;

That's one extra line, but a lot of easier to read code, and less code, if 
more comparisons start to be made regarding x and y.
