RE: Service programs no binder language signatures???

["Stone, Brad V (PP)" <bvstone@xxxxxxxxxxxxx>]

Think of signatures as file level identifiers for service programs.  In your
binder language, you can set it up so that it will have more than one
signature.  There are great examples in the online books to do this.  In a
nutshell, after you have added new subprocedures, do the following:
 
1.  Make a copy of all the binder language statements in a group.  On one of
them (the one you are not adding the new subprocedures to), change it to
read PGMLVL(*PRV).  
 
2.  On the other list, add your new subprocedures.  
 
Here's an example of binder language that will produce 2 signatures so that
the programs that use the old subprocedures will not have to be recompiled.
 
             STRPGMEXP                                  
             EXPORT     SYMBOL(SP1)                  
             EXPORT     SYMBOL(SP2)                 
             EXPORT     SYMBOL(NEWSP)                
             ENDPGMEXP                                  
             STRPGMEXP  PGMLVL(*PRV)                    
             EXPORT     SYMBOL(SP1)                  
             EXPORT     SYMBOL(SP2)                 
             ENDPGMEXP                    
 
Hope this helps...

Subject: Service programs no binder language signatures???


I have general question regarding modifying and adding code to a service
program. My question is this. If I for example add additional sub-procedures
to a given service program, do I have to rebind this service pgm to any of
the *pgm objects that are currently bound to this service pgm and don't even
use the new sub_procedures? The service program visibly has a different
signature than the signature seen in the service pgm detail on a display pgm
of the pgms previously bound to this service pgm.
Can anyone tell me if the signatures mean anything when not using binder
language. If so what are the ramifications of not rebinding the service pgm
in question. TIA Wayne Achenbaum
