data structure has no valid subfields

[Joel Fritz <JFritz@xxxxxxxxxxxxxxxx>]

I must be missing something simple and obvious.  I'm trying to use some
externally defined data structures based on several different record formats
in a display file.  When I compile the program I get a warning that
"*RNF3530 00      2 Data structure has no valid subfields.  " (This one
comes from a program that has two of them.)  The problem is that the fields
don't get defined in the program although the data structure does.  I wrote
a minimal test program with two data structures defined from the same
display file and got the same results.  For the sake of brevity I built a
display file that only includes abridged versions of the two record formats.
Same results.  Here's the code:

Display File:

  A                                      DSPSIZ(24 80 *DS3)
  A          R NAMADR
  A                                      OVERLAY
  A                                  4  2'Name         :'
  A            ADRNAME   R        O  4 18REFFLD(RREF/NAME U#LIB/U#REFP)
  A            ADRACCT   R     Y  O  4 49REFFLD(RREF/ACCT U#LIB/U#REFP)
  A                                      EDTWRD('   -   -   ')
  A          R SELECTOR
  A                                      OVERLAY
  A                                  4  2'Name:'
  A            SELNAM        30   B  4 13
  A                                  5  2'ZIP'
  A                                  5  6':'
  A            SELZIP         9A  B  5 13


Program:

D namescr       e ds                  extname(ci001dxxx : namadr  )
D selscr        e ds                  extname(ci001dxxx : selector)
C                   eval      *inlr = *on


Here's the part of the compile listing that's relevant:

                          S o u r c e   L i s t i n g

     1 D namescr       e ds                  extname(ci001dxxx : namadr  )
