RE: Scope of variables and subprocedures.

[Scott Mildenberger <Smildenber@xxxxxxxxxxxx>]

You can create functions, even at V3R7.  Here is a sample prototype and
procedure

 *********************************************************************
 ***  Returns the patron name or *blanks if not valid.                
 *********************************************************************
d dep_patron      pr            24                                    
d   patron                            const like(cust_t)              


p dep_patron      b                   export              
d dep_patron      pi            24                        
d   patron                            const like(cust_t)  
                                                          
c     patron        chain(n)  deplpatr                    
                                                          
c                   if        %found                      
c                   return    add1                        
c                   else                                  
c                   return    *blanks                     
c                   endif                                 
                                                          
p dep_patron      e
