Peering through the cob webs I'm comming up with nohalt for unprintable characters, but there as a little voice saying no, no, it's to allow for inquiry interrupt.....but then again..... ok ok, How about; How was CORE STORAGE INDEX defined in RPG > and what was it's use? The key value at the beginning of each track of the index portion of a file. The system could narrow down it's search to the nearest track. This index was retained in CORE STORAGE when you used to get your processor from a CORE house. It was originally used by the program specifying the index (S/34 F spec) then graduated to a system level resource automatically calculated and sharable by all programs (S/36 ocl). I think the math went something like (key length + 3) * #of tracks = storage index size It's a curse to remember even only half the details of stuff like this. Sometimes I wake up in the middle of the night, in a cold sweat, screaming "when will it stop!" =:-o * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * This is the Midrange System Mailing List!
