  > Using IMS Online Reorganization Facility
  >> HRFSYSIN DD statement keywords
  >>> GDGLIMIT keyword
  This topic has been updated as follows:
  This keyword specifies the maximum number of GDG (generation
  data group) data sets to associate with a model GDG. The
  GDGLIMIT keyword is optional for REORG HRFSYSIN DD statements
  and is not applicable to UNLOAD HRFSYSIN DD statements. The
  value specified on this keyword is used when both of the
  following conditions are true:
  - IMS Online Reorganization Facility is requested to dynamically
   allocate a GDG data set as an image copy data set or a log data
   set.
  - A GDG base for the specified GDG data set does not exist.
  Dynamic allocation of a GDG data set is requested if one or more
  of the following conditions are true:
  - ICDYN(Y) and ICTRLR(1) are specified.
  - ICDYN(Y) is specified, and the &GDG variable is specified for
   the IC1DSN keyword, the IC2DSN keyword, or for both keywords.
  - IEFRDER DD is not specified, and the &GDG variable is
   specified for the LOG1DSN keyword, the LOG2DSN keyword, or for
   both keywords.
  Before allocating a GDG data set, IMS Online Reorganization
  Facility verifies the existence of a GDG base. If a GDG base
  does not exist, IMS Online Reorganization Facility automatically
  defines one by using the GDGLIMIT keyword value as the number
  of generations to keep.

  > Using IMS Online Reorganization Facility
  >> HRFSYSIN DD statement keywords
  >>> GDGMODEL keyword
  This topic has been updated as follows:
  Use this keyword to identify a model for the GDG image copy data
  sets. The GDGMODEL keyword is optional for REORG HRFSYSIN DD
  statements, and is not applicable to UNLOAD HRFSYSIN DD
  statements. The value specified on this keyword is used only
  when both of the following conditions are true:
  - A GDG is requested for an image copy data set.
  - IMS Online Reorganization Facility dynamically allocates the
   image copy data set.
  The GDG model name (gdgmodel) must be the name of a cataloged
  image copy data set.

  The &GDG variable has been added to the list of supported
  variables, as follows:
  &GDG
  The identifier of the GDG data set. This variable must be
  specified in the last position in the pattern, and it should not
  be specified with variables related to date or time.
