Fields in externally described records can't be array names.
In the D-Specs, you're defining PDLB02 as an array.  Since
there's no DIM keyword on the D-Spec, why is PDLB02 getting
defined as an array?  Because it overlays an array.  Check
the cross-reference listing and you'll see that PDLB02 is
defined as a 3 element array.
