Mapping of constants in C

Also, cunhc contains a group of constants to establish the Collation rules. These are the constants.

Group 1 - Collation level:

These constants set up the Coll_Level, and must be specified individually.

DDA size:

#ifdef _LP64                                                            
 #define CUNBOPRM_DDA_REQ        8192                                   
#else                                                                   
 #define CUNBOPRM_DDA_REQ        4096                                   
#endif
