There is nothing in the directory entry called a volume definition
block. The ISPF data, if present, are in the user data field of the DE.
Record format, LRECL and BLKSIZE are kept in the DSCB1, not in the
directory, and apply to the entire PDS. You may be able to find the
layout of the ISPF data in the ISPF manuals, but I doubt it.
