摘要
In a data processing system, in order to provide its operating system with a better mechanism to identify and track addressing errors with a high potential to cause a storage overlay, it is first determined whether or not, a program interrupt has occurred. It is next determined whether or not this interrupt involves or occurs as a result of an address translation. It is then determined whether or not, the instruction involved calls for an update of storage. If it is determined that all three of these conditions are satisfied, then a flag is set in an area of storage accessible to the operating system so that it may provide a more specific event monitoring record.
