RE: SELECT & WHENEQ Question

Barbara,

That's a good point.  But you've missed one of the requirements the OP
said she needed.

The order, in this case 30,10,20 in which the values are checked matter.

Thus, I didn't feel a loop would be a good choice here, especially with
50 values.

Actually, as I write this, it occurs to me that the best (IMHO) way to
handle this would be to use a loop in this manner:
     d valuesToCheck   ds 
     d                                2a   inz('30')
     d                                2a   inz('10')
     d                                2a   inz('20')
     d  checkValue                    2a   overlay(valuesToCheck) dim(3)
     
     d x               s             10i 0
      /free
        x = 1;
        W@GOOD = *BLANKS;
        dou W@GOOD <> *BLANKS 
            or x > %elem(checkvalue);
          K@FAC = checkValue(x);
          EXSR $100;
          x = x + 1;
        Enddo;
        if W@GOOD = *BLANKS;
          W@GOOD = 'NO';
        endif;
      /end-free 

Thoughts?

You could certainly do it, but you'd have to short-circuit 

the for loop

with LEAVE since the for loop really isn't the controlling factor.
Plus you'd have to code to set W@GOOD to 'NO' if you make 

it all the way

through the loop.  The result is ugly, and not clear as to 

why your are

doing what you are doing.

It's interesting to consider the possible solutions if there were 50
possible values for K@FAC rather than just 3.  Using a nested 
loop would
get nasty.  Terri's current solution would possibly be better, since
it's flat, even though it's kind of ugly.  But a regular loop over the
values would be best (imho, best even with 3 possible values).

W@GOOD = *blank;
i = 1;
dow W@GOOD = *blank;
   K@FAC = candidate(i);
   exsr $100;
   i = i + 1;
enddo;
if W@GOOD = *blank;
   W@GOOD = 'NO';
endif;
