Don,

stored procedures do work with service programs:

Create function  mkrfxil2s(                             
  InCent    decimal(2,0),                               
  InYr      decimal(2,0),                               
  InSsn     char(2),                                    
  InBrand   char(1),                                    
  InMdm     char(2),                                    
  InItmnu   char(4))                                    
returns     char(256)                                   
external name 'LIBRARY/SRVPGM(PROCEDURENAME)'
Language        RPGLE

( I think they need the library qualifier which can be a bit of a bother. )

Another problem I had with calling RPG via stored procedures is that CHAR parm 
types caused a "procedure not found" error.  had to use VARCHAR instead ( which 
is varying in rpg ).
