Peter, first let me thank you for the education I couldn't get from the book. Again, I'm in the research phase and decided to drop the Lock and consider higher level serialization method. Sam, here is the definition of SRR from POP. When a common storage area larger than a doubleword is to be updated, it is usually necessary to provide special interlocks to ensure that a single program at a time updates the common area. Such an area is called a serially reusable resource (SRR). Thank you all and we can put this to rest. Sail Kim Vanguard Research Institute, Inc.
