To display or print a list of data sets on one or more disks, you can use the Work with VTOC utility. With this utility, you can list either all the data sets, or a subset of the data sets based on a generic data set name.

The VTOC command of DYNCAT is used to create and delete the VTOC indices used by the Dynam/D VSE component for Indexed VTOC support. Each VTOC Index is a small disk file containing an index to the entries in the unmodified VTOC for the device.

The volume table of contents (VTOC) is a data set that describes the contents of the DASD volume on which it resides. The VTOC locates data sets on that volume. The VTOC is composed of data set control blocks (DSCBs).

Allocating space for a data set causes system routines to examine the free space records, update them, and create a new VTOC entry. Data sets are always an integral number of tracks (or cylinders) and start at the beginning of a track (or cylinder).

In the storage architecture of OS/360 and successors, CMS, and DOS/360 and successors, the Volume Table of Contents (VTOC) is a data structure that provides a way of locating the data sets that reside on a particular DASD volume.

The Volume Table of Contents (VTOC) is Sector $00 (0) on Track $11 (17). This is the key sector from which all searches start out. Example: A typical DOS 3.3 Disk's VTOC sector

Another important mechanism that manages data on a computer system is the volume table of contents (VTOC). The VTOC keeps track of the locations of all data sets on a volume. You cannot find data sets without the VTOC, even if they exist on a volume.

VTOC Utility. The VTOC Utility screen performs one of the following two functions for a set of selected DASD volumes.

The LVTOC display provides an online Volume Table of Contents (VTOC) sorted by device address or a VOLID sorted by starting extent address. This Video will demonstrate how to view the VTOC by CUU or VOLID, view multi-extent files, and …
