The following example programs demonstrate a number of useful features of
the InterBase programming interface.

You should set the following environment variables before running
the examples:

ISC_USER       A valid username on the server.
ISC_PASSWORD   The password for the above user.
ISC_DATABASE   The path to the employee.gdb example database, including
	       server name.  For example, to connect to the NT server
	       named "NTserver" via NetBEUI:
		ISC_DATABASE=\\NTserver\C:\InterBase\examples
	       
	       This assumes that InterBase was installed to a
	       directory C:\InterBase on the server host.
	       (this is not the default install directory)

In addition, you should create a guest username "guest"
with password "guest" before running the api15 example.
Use gsec or IBConsole to do this.

Program     Description
---------   ------------------------------------------------------------------
stat1.e     Illustrates a simple update to an existing table.
stat2.e     Illustrates singleton select.
stat3.e     Illustrates a simple cursor -- declare/open/close/fetch.
stat4.e     Show 'declare table' and 'create table'.
stat5.e     Demonstrate 'update where current of'.
stat6.e     Select an array.

api16.c	    Demonstrate asynchronous event trapping
api16t.c    Identical to stat12t, this triggers the event for api16.

VARY struct is used by api3.c, apifull.c, and api14.e.
SQLCODE extraction from status is covered by several programs.
Zero transaction handle is covered in several programs, ex. api14.e.
