Abstract
An apparatus and method for implementation in a computing system (5) which allows the transfer of control from one process (10) to another process (40). The input/output supervisor (20) and a newly provided control mechanism (50) are used to switch control. Transfer of data between the two processes is carried out using a data pool (75). This data pool (75) is accessible to both processes (10, 40) through the control mechanism (50).
