  * PROBLEM DESCRIPTION:                                         *
  * Customer has used the double byte character set (DBCS) as a  *
  * character encoding system in database schemas for non-Latin  *
  * scripts.                                                     *
  * Java Metadata Class supports the marshal attribute DBCS of a *
  * FIELD statement of a SEGM statement of a DBD definition.     *
  * Customer migration to IMS Managed ACBs discovered IMS        *
  * catalog does not support DBCS.                               *

Problem conclusion

• Catalog enhancement to support DBCS.
  Added the new parameter PUREDBCS=Y|N to DBDGEN DFSMARSH
  statement and PUREDBCSYES | PUREDBCSNO to DDL CREATE TABLE
  statement ims-column syntax.
  PUREDBCS specifies a DATATYPE=CHAR field in the marshall
  attribute specification.
  The new information is stored in the DBDLIB, ACBLIB, IMS
  directory, IMS catalog database.
  Updated catalog writers or readers to build or retrieve the
  information as required:
  . Catalog populate utility DFS3PU00 reads input ACBLIB and
  migrates new option to catalog.
  . Data Definition utility DFS3ID00 reads input DDL statements
  and dynamically builds new option to catalog.
  . Library builder utility DFS3LU00 reads input directory and
  builds new option back to sources.
  . Directory recovery utility DFS3RU00 reads input catalog
  databases and recovers new option back to directory.
  . Catalog API DFS3CATQ: retrieves new option from directory.
  . DB DLI API Get unique record GUR retrieves new option from
  catalog database.
  . DDL generation batch utility reads catalog and builds new
  option back to DDL statements.
  . IMS Explorer for developers E4D manages new option in catalog.
