Reading a Subset of Directory Information

To obtain a subset of directory information for each selected data item, code DIRINFOFMT=NAMELIST.

For each data item, the system returns a 32-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
The number of cache structure elements allocated to the data item

Macro IXLYCANB maps the 32-byte directory block. For a description of IXLYCANB, see z/OS® MVS™ Data Areas in the z/OS Internet library.

The system also indicates in field CAADIRCOUNT of the answer area a count of the number of directory blocks for data items returned to the local cache buffer.
