One merit is the ability to use the procedure in an expression.

ex.

D RtvBirthDay           PR              10D    DatFmt(*ISO)
D     Person                                     30       const

D SendMsg               PR
D   MsgText                                    80       const

C         Select

C         When            CurrentDate < RtvBirthDay( MyWife )
C                             Eval                   MessedUpAgain = *off
C                             Eval                   MsgText = 'Work Late.  No 
reason to rush tonight.'
C                             CallP                  SendMsg( MsgText )

C                             When                CurrentDate = RtvBirthDay( 
MyWife )
C                             Eval                   MessedUpAgain = *off
C                             Eval                   MsgText = 'If you don't go 
home on time, you'll be sorry.'
C                             CallP                  SendMsg( MsgText )

C                             Other
C         Eval                  MessedUpAgain = *on
C         Eval                  MsgText = 'It's going to be a bad night. You 
might want to stay and work.'
C                             CallP                  SendMsg( MsgText )

C                             EndSL
