DS1DSPAC shows you the original _units_ (trk, cyl, average block). As far as I know (and as others have said) nothing will show you the original _number_ of those units requested for the primary allocation, which seems to be the OP's desire. Even ISPF does not claim to show you the _primary_ allocation. It shows, as mentioned by the OP earlier, the value of the "1st extent". The primary allocation is made up of a first extent and up to 4 other extents. ISPF just shows the size of the first extent, which in many cases will be some value less than or equal to the requested primary space. (But if adjacent extents have been collapsed together it could, I suppose, be a value greater than the requested primary space.) -- Walt ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
