COMMENTS : A directory generic data block can be
considered to consist of 2 overlapping entities.
The "generic block" is the entire block and includes
the generic header and a variable length "data
block". The data block is identified by the DGDID
field and is usually mapped by its own DSECT.
These blocks are written to the directory DASD
by HCPDIR's generic write routine, and they are
read and handled by the directory generic read
