<p>A linked procedure call mechanism for replacing an old software unit (102) with a new software unit (104) without disturbing the ongoing activities of the overall system. The linked procedure call mechanism includes a trader (80) which directs the system execution processes towards either the old software unit (102) or the new software unit (104), depending on when the process was created. Processes created prior to initiation of replacement will continue to use the old software unit (102), while processes created after the initiation of replacement may be directed to use the new software unit (104). When the activities within the old software unit (102) have ended, the replacement is complete and the old software unit (102) can be removed from memory.</p> |
