+ NAME
+ cdemo81.c - Basic OCI V8 functionality
+
+ DESCRIPTION
+
+ * An example program which adds new employee
+ * records to the personnel data base. Checking
+ * is done to insure the integrity of the data base.
+ * The employee numbers are automatically selected using
+ * the current maximum employee number as the start.
+ *
+ * The program queries the user for data as follows:
+ *
+ * Enter employee name:
+ * Enter employee job:
+ * Enter employee salary:
+ * Enter employee dept:
+ *
+ * The program terminates if return key (CR) is entered
+ * when the employee name is requested.
+ *
+ * If the record is successfully inserted, the following
+ * is printed:
+ *
+ * "ename" added to department "dname" as employee # "empno"
+
+ Demonstrates creating a connection, a session and executing some SQL.
+ Also shows the usage of allocating memory for application use which has the
+ life time of the handle.
+
+ MODIFIED (MM/DD/YY)
