Data Structure Parameters in RPG Prototypes

November 15, 2002 Hey, Ted

Hey, Ted:

Back in my RPG III (RPG/400) days, it was easy to define an entry parameter as a data structure.

IPARM1      DS 
I                                       1   8 ACTION 
I                                       9  10 CODE

C                    PARM           PARM1

I used this same method in RPG IV before I started prototyping entry parameters.

D Parm1          DS 
D  Action                1      8  
D  Code                  9     10  
D  RtnVal               11     12  0 
I*  
C     *entry       plist                        
C                  parm                    Parm1

Now I prototype entry parameters, as you described in the November 16, 2001 issue of Midrange Guru. Since the D-spec for …
