       D  MyData                       Dim( 999999 ) Ascend
       D  Field1                  6p 0 Overlay( Data: *next ) Inz
       D  Field2                  1a   Overlay( Data: *next ) Inz
       D  Field3                   n   Overlay( Data: *next ) Inz

  * USERS AFFECTED:                                              *

  * PROBLEM DESCRIPTION:                                         *
  * Data structures lengths and subfield positions did not       *
  * respect the OVERLAY, ALIGN or POS keywords.                  *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The lengths computed for ILE RPG data structures and subfields
  did not take into account the OVERLAY, ALIGN or POS keywords or
  the from position specified in the fixed columns.  This could
  manifest itself with incorrect field lengths or in some cases
  subfields will be shown as "Unknown(0)" in the outline view.
  For example in the data structure below, the "Data" field will
  end up having a zero length and appearing in the outline view as
  "Unknown(0)"
       D  myDs                    DS
       D  Data
       D  Field1                  6p 0 Overlay( Data: *next ) Inz
       D  Field2                  1a   Overlay( Data: *next ) Inz
  

Problem conclusion

• This problem is fixed in the RDi 9.1.1 update.
