Offsets Name Length Format Description
44 2C SMF14SDC 1 binary Size of DCB/DEB section.
45 2D SMF14NUC 1 binary Number of UCB sections. There is always one UCB section for each UCB currently processing except for ISAM and BPAM-concatenated data sets. For ISAM data sets, this field is calculated as: one for the index extent, one per volume for primary extents, and one for the overflow extent. For BPAM there is one UCB section for each data set in the concatenation except that any z/OS® UNIX directories are omitted. For extended format data sets, there is one UCB section for each volume.
46 2E SMF14SUC 1 binary Size of each UCB section.
47 2F SMF14SET 1 binary Size of ISAM extension section. This field equals 28 (or 0 if there are no ISAM data sets). For PDSE data sets, this field will always contain X'0'.
48 30 SMF14OPE 4 binary Time since midnight, in hundredths of a second, when the data set was opened.
