IEHLIST Sample Output

Figure 1 is a listing of a volume table of contents from an extended format sequential data set. The VTOC listing of an extended format sequential data set will differ from that of sequential and partitioned data sets and PDSEs. Figure 2 is a IEHLIST VTOC listing that is typical for a sequential or partitioned data set, or a PDSE. The primary difference between these two kinds of VTOC listings (extended format sequential data sets and all other types of data sets) can be found in the LAST BLK field of the outputs. In addition, if IEHLIST is producing a VTOC listing of an extended format sequential data set, the attribute E will be included under the field SMS.IND. For more information on the characteristics of extended format sequential data sets, see z/OS DFSMS Using Data Sets .

A detailed explanation of the fields in the VTOC listing follows the figures. Please note that the explanation of the LAST BLK field contains two different entries—one for an extended format sequential data set (TTTT-R), and one for a sequential or partitioned data set, or PDSE (T-R-L).

Please note also that the following figures are only examples of IEHLIST VTOC listings. Your actual VTOC listing produced by IEHLIST will differ.

For VSAM data sets, the LAST BLK(T-R-L) field might be blank.
