Reading All Directory Information

To read all directory information for each selected data item, code DIRINFOFMT=DIRENTRYLIST.

For each data item, the system returns a 128-byte block of directory information to your local cache buffer. Each block consists of the following information:

Data item name
Contents of the user-data field for the data entry
The number of the storage class to which the data item is assigned
An indication of whether the data item is marked changed or unchanged
An indication of whether there is data stored in the cache for the data item
The parity assigned to the data item
The state of the cast-out lock
The contents of the cast-out lock
The number of the cast-out class to which the data item is assigned (valid only if the data entry is marked changed or locked for cast out)
The number of cache structure elements allocated to the data item
A bitstring that indicates registration of interest in the data item for all users.

The mapping macro IXLYDEIB maps the 128-byte directory block. For a description of IXLYDEIB, see z/OS® MVS™ Data Areas in the z/OS Internet library.

In the answer area field CAADIRCOUNT, the system also provides a count of the number of directory blocks returned to the local cache buffer.
