  * USERS AFFECTED:                                              *
  * All IMS 15.3 users using DDL.                                *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * zDDL new enhancements. During the creation of large volume   *
  * of Programviews using IMS CREATE DDL, ABENDS0C4 happens in   *
  * the DFS3TR20 module.                                         *

  * INSTALL CORRECTIVE SERVICE FOR APAR/PTF                      *
  ****************************************************************
  zDDL enhancements
  1. DYNAMICPROGRAMVIEW control option to support the creation of
  DOPT programview.
  2. IMSSQL DD support for in-line concatenation with single or
  multiple data sets.
  3. Write records to SYSPRINT per COMMIT scope to facilitate the
  tracking of long running job with multiple COMMIT DDLs. Error
  details are printed next to the failing DDL statement.
  4. Comments support in IMSSQL DD input DDL statements.
  5. Asterisk (*) to comment-out SYSINID control options.
  6. If user supplied a DFSTAT DD card, then DDL driven DL/I call
  count was not accounted and IR call was missing in the PST
  Accounting Statistics.
  7. If user supplied a DDLTRACE DD card, then DDL events were
  written to DDLTRACE data set but the job report containing DDL
  statements, warnings, and error details was also routed to the
  DDLTRACE DD instead of SYSPRINT.
  Problem 1
  During the creation of large volume of Programviews via CREATE
  DDL statements, if most of the programviews has one of the
  CREATE SCHEMA on very large database, then 0C4 abend happens in
  DFS3TR20 because wrong buffer was released.
  

Problem conclusion

• DFS3ID00 was changed to support new zDDL enhancements.
  DFSDDL10, DFSDDL30, DFS3DL40, DFSDL50, DFSOLC00, DFS3DMU0, and
  DFSOLC70 were changed to support dynamic programview via zDDL
  utility.
  DFS3TR20 was changed to release the correct MCR buffer.
  DFS3DL10, DFS3GUR0, DFSSBSP0, and DFSIDR00 were changed to
  capture zDDL DLI call accounting statistics.
  BPEZRDP0 and  BPERDPD0 were changed to support mixed mode IMSSQL
  DD card.
  DFS3RQST, DFSOLCD, and DFSAIBEQ macros were changed to support
  dynamic programview via zDDL utility.
