Re: read on a do loop

[rob@xxxxxxxxx]

a)  Caught that right after I sent it.  :-)
b)  You're right on the dow vs dou.  Thanks.
c)  I like the %status in case I decide to use the subprocedure on more 
than a do loop.  Hair bit more informational in that case.

I'd like to see the SELECT statement with the flexibility of sql's CASE 
statement.  In sql I can do:

select field1,
       case
         When TotAmt <= 100 Then 'Small'
         When TotAmt <= 500 Then 'Medium'
         Else                    'Large'
       End As SaleSize
>From Sale

or

Select field1,
       case TotAmt
         When <= 100 Then 'Small'
         When <= 500 Then 'Medium'
         Else             'Large'
       End As SaleSize
>From Sale

That way I don't have to execute a subprocedure potentially multiple 
times, or store the return into a work variable.  Translated to rpg:
Select;
When ReadLoopProc()=00012; // this error occurred
  // Then do this
When ReadLoopProc()=00000; // ok
  // Then do the other
Other;
  // Handle unknown error
EndSl;

Becomes:
Case ReadLoopProc();
When 00012; // this error occurred
  // Then do this
When 00000; // ok
  // Then do the other
Other;
  // Handle unknown error
EndCase;
