Watch Support

The Watch support provides the ability to stop program execution when the content of a specified storage location is changed. The storage location is specified by the name of a program variable. The program variable is resolved to a storage location and the content at this location is monitored for changes. If the content at the storage location is changed, execution stops. The interrupted program source is displayed at the point of interruption, and the source line that is highlighted will be run after the statement that changed the storage location.
