RE: Overlay an External DS

Joel, this failed for me, showing both the data structure and the array
as all blanks:

ddsElems        e ds                  extname(elems)           
d  array                        10    overlay(dsElems:1) dim(4)
                                                               
c/exec SQL declare c cursor for select * from elems            
c/end-exec                                                     
c/exec SQL open c                                              
c/end-exec                                                     
c/exec SQL fetch next from c into :dsElems                     
c/end-exec                                                     
C     array(2)      dsply                                      
c/exec SQL close c                                             
c/end-exec                                                     
C                   eval      *inlr = *on                      


But, if I change it thus, it works fine:

ddsElems        e ds                  extname(elems)           
d  array          s             10    dim(4) based(@)
d  @              s               *   inz(%addr(dsElems))


I see the second field of the first record.  Bizarre.
