IIRC, the top byte of the ETOD is documented as "reserved" or "undefined". We can guess. We can be wrong. So as far as is (was) currently documented, the ETOD overflows at the same time as the old TOD.
Description of STCKE behavior: The current value of bits 0-103 of the TOD clock is stored in byte positions 1-13 of the sixteen-byte field designated by the second-operand address, provided the clock is in the set, stopped, or not-set state. Zeros are stored in byte position 0. The TOD programmable field, bits 16-31 of the TOD programmable register, is stored in byte positions 14 and 15. The operand just described has the following format: .-----+-----------------------------+----------. | | |Programm- | |Zeros| TOD Clock |able Field| '-----+-----------------------------+----------' 0 8 112 127 -- Edward E Jaffe Phoenix Software International, Inc 831 Parkview Drive North El Segundo, CA 90245 310-338-0400 x318 edja...@phoenixsoftware.com http://www.phoenixsoftware.com/ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
