Your question is slightly ambiguous. Do you want to know how many tracks the datasets occupy or how many tracks each dataset would take with no holes due to replaced/deleted members and no unused tracks at the end? If the former, the z/OS 1.11 version of ISPF 3.4 has an option to total the tracks for all datasets that are displayed in the list. If the latter, how accurate do you need to be? The number of tracks needed to hold x KB varies depending on the block size (or more precisely, the number of bytes in each block, which need not be the same even for FB). You can get a reasonable approximation for the number of tracks with (number of bytes)/56K (rounding up). ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
