** PURPOSE :
** This program is an example of how APIs are implemented in order
** to CREATE a DATABASE with a user-defined collating sequence,
** then DROP the DATABASE.
**
** A user-defined collating sequence allows the user to specify
** the collating behaviour of the database. This can be used by
** applications that require compatibility to the collating
** behaviour of host database products. For example, simulating
** the collating behaviour, in a DB2/MVS CCSID 500 (EBCDIC
** International) database, in a DB2/CS codepage 819
** (ISO Latin/1) database, can be achived by specifying
** a collating sequence that maps codepage 819 characters
** to CCSID 500 characters when the database is created.
**
** APIs USED :
** CREATE DATABASE sqlgcrea()
** DROP DATABASE sqlgdrpd()
