Ray,

Define a DS in the D-specs and define an array in that. Overlay the DSPF fields
to the datastructure. I think code would look like that (no real example by
hand):

D Screen                               DS                          335
D   Array                                                                  5
DIM(67)
D     DspField1                                                         5
OVERLAY(Screen:1)
D     DspField2                                                         5
OVERLAY(Screen:*NEXT)
 etc, etc.

Hope this will help.
