This article describes a method for anticipating events and conditions that may occur during a PC-Host session when the PC application is simulating a user's interactions. Host applications and systems are frequently designed with the expectation that a user will be able to respond to unusual situations, such as when another screen is ready to be displayed. However, when a program simulates the user, the situation is more complex. The Professional Work Manager (PWM) provides a facility that allows its users to create procedures called Activities. These Activities have the ability to interact with a Host system or application on behalf of the user. An Exception is an unexpected event that inhibits the Activity's execution. PWM makes it possible to anticipate unusual situations and predefine how to handle them.
