Hi, I was reading the manual for an explanation of CPU lock:
CPU lock -- provides MVS-recognized (valid) disablement for I/O and external interrupts. The manual gives a further explanation: MVS does not guarantee preservation of the interrupt status of programs that explicitly disable for I/O and external interrupts through the STNSM instruction. What does 'does not guarantee' mean? Thanks.
