/* Initialize the c-tree system */

if (InitCTreeXtd(10,2,4,10,USERPRF_NTKEY,"admin","ADMIN","FAIRCOMS"))

terminate("Could not initialize c-tree",-1);

if (argc > 1)

db_create(); /* create the database files */

db_init(); /* open the database files that are already created */

database(); /* perform database routines */

db_close(); /* close the files, and any other ending stuff */

fflush(stdout);

return(0); /* dummy to remove compiler warning */

}

/********************************************************

* *

* db_init: Open the data files and indices. They *
