specifies the data set organization as one of the following codes.
Each code indicates that the format of the device dependent portion
of the data control block is to be similar to that generated for a
particular access method:

Note: For direct-access devices, if you specify either PS or PO, you
must maintain the following fields of the device dependent portion of
the data control block so that the system can write a file mark for
output data sets:
• The track balance (TRBAL) field, which contains a 2-byte binary
nuwber that indicates the remaining numter of bytes on the current
track •
•
The full disk address (FDAD-MBBCCHHR) field, which indicates the
location of the current record.
IOBAD=relexp
specifies the address of an input/output block (lOB). If a pointer
to the current lOB is not required, you may use this field for any
purpose.
