ABSTRACT:
A method and system of monitoring data structures in a computer system. A control block is established when a user obtains access to the computer system and is released when the user releases access to the computer system. A control program is provided to control operation of the computer system, and the control program has a plurality of process modules to service the control blocks. The method comprises the steps of invoking one process module to service one control block, and temporarily suspending operation of that one process module and invoking another process module to control operation of the computer system. A monitoring unit is established to indicate whether that one control block remains established. When control of the computer system is passed from the other process module back to said one process module, the monitoring unit is searched to determine whether the one control block is still established. If that control block is still established, operation of the interrupted process module is resumed; however, if the one control block is not still established, control of the computer system is passed from the one process module to the control program.
