      EXEC SQL EXIT END-EXEC.

The exit statement closes all connections that your program opened. Also, exit deallocates all Embedded SQL resources and Client-Library resources allocated to your program.
Although the exit statement is valid on all platforms, it is required only on some. For more information, see the Open Client/Server Programmer’s Supplement.
You cannot use Client-Library functions after using the exit statement, unless you initialize Client-Library again. See the Open Client Client-Library/C Programmer’s Guide for information about initializing Client-Library.
The exit statement is a Sybase extension; it is not defined in the SQL standard.
