James, since you're pre-V5R1, you would code something like this:

P get_data          b
D get_data          pi
D    ds_parm                  100
D ds                ds               based(pDs)
D   field1                      5p 0
D   field2                     10i 0
c           eval     pDs = %addr(ds_parm)
c           z-add    data        field1

It's better in V5R1.

(z-add???  Yikes!)
