Actually, it makes sense when you multiple posibilities that fall into a
single category. For instance, a negative number could indicate an error
category -- any error. So for instance, your procedure might have the
following as possible error return codes:

-1 = Error condition 1
-2 = Error condition 2
-3 = Error condition 3
-4 = Error condition 4
-5 = Error condition 5

Here's a couple of examples code snippets. You tell me which is more
intuitive as you're just reading through code.

Example A:

 ...
C              Eval     RtnCode = MyProc( MyParm )
C              Select
C              When     RtnCode > 0
 ...
C              When     RtnCode = 0
 ...
C              When     RtnCode < 0
 ...
C              EndSl



Example B:

 ...
C              Eval     RtnCode = MyProc( MyParm )
C              Select
C              When     RtnCode = ExistingCust
 ...
C              When     RtnCode = NewCust
 ...
C              When     RtnCode = Error
 ...
C              EndSl

They're not supposed to be indicator fields. It's actually numeric
fields. Cut and paste woes!

Maybe we need an IS construct.

C              When     RtnCode Is ExistingCust
