Mystic day is on Friday... What is a "totals" REXX? All values differ by a factor 1.024, you should have seen this yourself and drawn your own conclusions. Robert -- Robert AH Prins robert(a)prino(d)org ---------------------------------------------------------------------- This again raises the 1000 / 1024 problem. IIRC, ISMF complicates this even more by dividing once by 1000 and then each time by 1024 to convert from bytes to kbytes, Mbytes and Gbytes. And even the bytes number can cause discussion: how many bytes do you calculate for a track: the physical limit of 56664, as ISMF does but which is impossible to achieve or the real achievable number dependent on blksize, e.g. 55840 for lrecl=80. However, when you are consistent in your calculations, all will give the same percentage. I don't worry about those details: we manage many TB's and don't care if they are 68%, 70% or 72% filled, this is fine and 88%, 90% and 92% are both bad.
