RE: Passing a multiple occurrence datastructure from a procedure

One thing about MODS....  There is an implied cursor built in to RPG, that you 
use to control the memory location you want to access in the MODS...  When 
passing an ENTIRE MODS, you must always set the occurance  value to 1, so that 
you are pointing to the beginning of the MODS.  

Another option worth reviewing is to change the Multi-Occurance DS to an Array 
DS.  They result in the same use of storage, and I like the array syntax better 
than MODS.

Subject: Passing a multiple occurrence datastructure from a procedure


Hi,

 

I'm having troubles with passing a multiple occurence data structure as
a parameter to a subprocedure.  Can anybody help me ?

 

I have a subprocedure where I use a multiple occurrence datastructure
with 2 occurrences : the first occurrence is filled with the mailing
address of a client, the second with the delivery address.

However when I pass this datastructure, it seems as if I get only the
first occurrence.  My procedure interface looks like this :

 

D GetPatLoc       PI                                     

D Ref1                                Like(Ref1Kc) Const 

D Ref2                                Like(Ref2Kc) Const 

D Loca                                LikeDs(Location)   

                                                          

D Location        DS                  Occurs(2)          

D ... 

 

 

What am I doing wrong ?
