RE: Indicator enhancements (was Bale, Dan)

Me, I'd just junk the defined constants and use literals in the expression.
That way I don't have to bother looking up the D-specs to see how the
constants are defined.

C              Eval     RtnCode = MyProc( MyParm )
C              Select
C              When     RtnCode = 'ExistingCust'
 * Perform existing customer processing
C              When     RtnCode = 'NewCust'
 * Perform new customer processing
C              When     RtnCode = 'Error'

Gary, I don't see that *NEGATIVE appears to have general
usefulness.  Aside from that, indicators hold boolean values.
If you want to return more than 2 different values, use a
type that has more than 2 values, and use named constants
for your special values, in both your procedure and its
callers.

D Error        C         -1
D ExistingCust C         1
D NewCust      C         0

C              Eval     RtnCode = MyProc( MyParm )
C              Select
C              When     RtnCode = ExistingCust
 * Perform existing customer processing
C              When     RtnCode = NewCust
 * Perform new customer processing
C              When     RtnCode = Error
