RE: Passing a multiple occurrence datastructure from a procedure

The LIKEDS keyword does not inherit the OCCURS() keyword.
Add OCCURS to the parameter definition.

Johan,

When you pass a multiple occurrence data structure, you only pass the
current occurrence. The better alternative (v5r2 and up) is to pass a
data structure array. If that alternative is not available, you need to
use %Addr(Location) to get a pointer to the multiple occurrence data
structure in the caller. The subprocedure will need to accept that
pointer as one of its parameters. The subprocedure also needs to have
another multiple occurrence data structure (defined like the one in the
caller) based on the pointer parameter. It's clumsy, but it works.

HTH,
Roger Mackie

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 ?
