Barbara,

I'm still missing something.  Maybe I'm not explaining it correctly.

In your example the data structure is being passed as a parameter.  What I was 
trying to do was define the data structure inside the subprocedure.  I have 
modified your example to try and better show what I mean.

Fpf1       if   e             disk                    

D subproc         pr                                  
 
c                   callp     subproc
C                   return                            

P subproc         b                                   
D subproc         pi                                  

D ds              ds                  likerec(rec1) 

c                   eval      fld1 = 'x'              
c                   eval      ds.fld1 = 'y'           
c                   read      rec1          ds      
c     ds.fld1       dsply                   fld1      

P subproc         e

Rick, here's an example (that compiles on V5R2) of using a
locally-defined LIKEREC DS in a subprocedure.

The first record in my file has 'a' in fld1.  The program displays
   DSPLY  a    x

Fpf1       if   e             disk                    
D subproc         pr                                  
D   parm                              likerec(rec1)   
D ds              ds                  likerec(rec1)   
c                   eval      fld1 = 'x'              
c                   eval      ds.fld1 = 'y'           
c                   callp     subproc (ds)            
c     ds.fld1       dsply                   fld1      
C                   return                            
P subproc         b                                   
D subproc         pi                                  
D   parm                              likerec(rec1)   
c                   read      rec1          parm      
P subproc         e
