**
**    PURPOSE :
**       This program is an example of how APIs are implemented in order to
**       CREATE a DATABASE with the EBCDIC 037 standard collating sequence,
**       then DROP the DATABASE.
**
**       A user-defined collating sequence allows the user to specify the
**       collating behavieour 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 of DB2/MVS CCSID 500 (EBCDIC International)
**       can be achived by specifying a colating sequence that maps
**       codepage 819 characters to CCSID 500 characters when the
**       database is created.
**
**    APIs USED :
**       INSTANCE ATTACH                  sqleatin()
**       CREATE DATABASE                  sqlecrea()
**       DROP DATABASE                    sqledrpd()
**
**    STRUCTURES USED :
**       sqlca
**       sqledbdesc
**       sqledbcountryinfo
**
**    OTHER FUNCTIONS USED :
**       'C' COMPILER LIBRARY :
**          stdio.h  -  printf
**
**       external :
**          check_error :     Checks for SQLCODE error, and prints out any
**          [in util.c]          related information available.
**                               This procedure is located in the util.c file.
**
**
**    EXTERNAL DEPENDENCIES :
**       - Compiling and linking with the IBM Cset++ compiler (AIX and OS/2)
**         or the Microsoft Visual C++ compiler (Windows) 
**         or the compiler supported on your platform.
**       - a database by the name of "DBUDCS" does not exist.
