**    PURPOSE :
**       This sample program is an example of how to use the
**       Set Runtime Degree API (sqlesdeg).
**
**    APIs USED :
**       Attach to Instance (sqleatin)
**       Set Runtime Degree (sqlesdeg)
**
**
**    STRUCTURES USED :
**       sqlca
**
**    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.
