<p>Assume that a main routine sets savepoint A and then invokes a subroutine

that sets savepoints B and C. When control returns to the main routine, release

savepoint A and any subsequently set savepoints. Savepoints B and C, which

|
|
were set by the subroutine, are released in addition to A.</p>
