That's a new toy for those with the shiny new OS.

Subject: Variable Dimension Data Structure?

A while back someone posted about a new RPG featuer to define a variable dimension array. I think it was something like

dcl-s myArray dim(*AUTO:maxSize);

I have JSON DS setup as follows... the "orders" array is controlled by my HTTP request (i.e. I ask for maximum of 20). However, the API I'm consuming does not indicate any limitations on items within an individual order. So I was hoping to use the above on my "items" DS below.


dcl-ds json qualified;
count_orders int(5) inz;
dcl-ds orders dim(%elem(orderIDs_t));
id varchar(20);
state varchar(20);
count_items int(5) inz;
dcl-ds items dim(200);
id varchar(20);
product_id varchar(15);
product_name varchar(30);
product_option_id varchar(15);
sku varchar(15);
quantity int(5);
price_cents int(10);
end-ds items;
dcl-ds address;
.... And so forth

I'm on v7r3... is this possible?? RDi doesn't like the definition and it won't compile on our v7r3 system.

Thanks,
Greg
