Patrick,

When you overlay an array, the result is automatically an array as well.
What you can do is this:

D                 ds
DPdLb_fld
DPdLb01                               Overlay(PdLb_fld:*NEXT)
DPdLb02                               Overlay(PdLb_fld:*NEXT)
DPdLb03                               Overlay(PdLb_fld:*NEXT)
DPdLb                                 Like(PdLb01) Overlay(PdLb_fld) Dim(3)

You create a dummy field that contains the array (I think the compiler
calculates the length for you).  You make the individual fields overlay the
dummy field; you don't have to supply the definition if they are defined
elsewhere (externally described file); by using *NEXT you don't have to
worry about the positions either.  Lastly you create an array that overlays
the dummy field (and thus the individual fields) by not specifying *NEXT or
a position (or by specifying ':1').
