Julian-calendar leap years are defined very simply as those that have serial numbers divisible by 4, those in the doubly infinite sequence . . . -12, -8, -4, 0, +4, +8, +12 . . . A four-year Julian-calendar cycle thus contains a mean of (3 x 365 + 1 x 366)/4 = 365.25 days. This is

No, I'm not trying to release space that isn't there! LOL These datasets definitely occupy space. A typical dataset is 150 tracks of which 5 are in use. The volume list shows as CCXZ08 * * so presumably all of the 150 tracks are on CCZZ08 and that is where I want to release space (not on * and

Leap seconds deal with accumulating precession that is not dealt with effectively by the definition of the Gregorian calendar. I don't *think* so. I think they deal with the rotation of the earth on its axis taking more than 24 hours, as opposed to a rotation around the sun taking more than 365

Here I was dealing with the precession of the vernal equinox. The position of the sun at the time of the vernal equinox is slowly shifting westward in the sky. This is a standard, not at all arcane usage. I don't think Charles Mills knows much about what he is talking about in this case, but I

They are allocated in tracks. (I am familiar with how ISPF 3.4 reports space in tracks even though the dataset may be allocated in cylinders. So a dataset reported as 150 tracks, with 5 occupied, might be expected to come down to 15 tracks, not 5.) They are utterly vanilla PS FBS 27920. The ISPF F

Then from that message I would suggest that the candidate volumes prevent the freeing of space. So how is your DataClass set up for this file? For a multivolume data set that is not in extended format, or is in extended format with a stripe count of 1, CLOSE releases space only on the current
