Without seeing your attempted c doing it is hard to guess what was wrong.

Maybe someone else who does what you were trying to do has an example they can post - I don't have any I'm afraid.

Jon,

What you're missing (what I may have left out) is that I the procedure is running an SQL statement to retrieve data from up to 20 rows. I was having trouble defining things so it would compile.

I was trying to define a third parameter - ouShip likeds(ship) - so that the SQL statement populated that parameter. I tried quite a few things, but couldn't get it to compile.

Error: SQL5011 Position 65 Host structure array OUSHIP not defined or not usable. Reason: The host structure is not a dimensioned array.

I ended up just defining it in the main program and updating that directly in the procedure (rather than passing it)... but I hated doing that.

Subject: Re: How best to pass a DS or DS Array

I'm having trouble with the logic of this.

If you had simply passed the DS _as_ a parameter a pointer to the DS would have been passed. It seems you're doing a bunch of work to no effect.

In the prototype and the PI simply specify the parameter as LikeDS(dsNameGoesHere).

what am I missing?

I had a similar issue and resolved it using pointers. I assigned the
pointer to the DS/Array. Then I just passed the pointer to procedure
as the parameter instead of the DS/Array.

dcl-s array_ptr POINTER ;
dcl-ds Array_ds occurs(5000) based(array_ptr) ;

parameter that is passed is array_ptr

In called subprocedure (program, etc)
- receive parm_array_ptr

dcl-s sub_array_ptr Pointer ;

dcl_ds Array_ds occurs(5000) based on (sub_array_ptr)

sub_array_ptr = parm_array_ptr

Since you are using the same address, all the changes will be there
when you return.

I don't know why I always struggle with this

I have created a sub procedure that uses an SQL cursor to gather a
list of ID numbers (see below). I mean this will work if I move the
DS definition to the main part of the pgm

So my question is how to define a parameter to return this data to
the main part of the pgm?
And how do I define the variable in the main part of the pgm?


dcl-pi CheckShipIDs;
inPID like(phpid#) const;
inPO like(phpo#) const;
end-pi;


dcl-ds ship qualified dim(10);
id char(20);
end-ds;
dcl-s maxrows uns(5) inz(%elem(ship));

Exec Sql
Declare pscsr Cursor for
Select distinct(psidcd) from POSDQPS
exception join ADRESSAD on adent#=:wkent# and adaltk=:psidcd
where pspid#=:inPID and pspo#=:inPO;

Exec Sql Open pscsr;
Exec Sql Fetch Next from pscsr For :maxrows Rows into :ship;
