Comments

• The following modules and a macro have been added.
  DFRCSPNA - The spanned log record process module
  DFRICTLA - The control block initialization controller
  DFRLDBDA - The database directory log processor
  DFRSPANA - The spanned log record process request macro
  *
  The following modules and macros have been modified.
  DFRCSELA - It changed so that it might be called by the DFRICTLA
             module.
  DFRCTLA0 - The Control block initialization process was moved to
             DFRICTLA module. And The processing which calls
             DFRICTLA module was added before calling DFRLCTLA
             module.
  DFRGAL1A - The DFRICTLA module was added to the module which
             calls this module.
  DFRGRD1A - The DFRICTLA module was added to the module which
             calls this module.
  DFRIDMBA - The processing of a MODBLKS data set was deleted.
             And it changed so that it might be called by the
             DFRICTLA module.
  DFRIGOCA - The processing of a MODBLKS data set was deleted
             except for the processing which checks the format of
             the MODBLKS data set information in the record of an
             OLCSTAT data set.
  DFRIMDSA - The processing of a MODBLKS data set was deleted
             except for the processing which checks the format of
             the MODBLKS data set information in the record of a
             MODSTAT data set.
  DFRINTFA - It changed so that it might be called by the DFRICTLA
             module.
  DFRLCTLA - The IMS Version check of X'4001' log record and the
             call process of a DFRLOLCA module were moved to
             DFRICTLA module.

             deleted.
  DFRRSCDA - It was reconstructed by change of a DFRRSCA macro.
  DFRCOPYR - The 'change date' of the copyright for modules was
             changed.
  DFRRSCA  - New V-CON fields for new modules were added.
             A new RSCDSLBT field was added for the address of the
