If you specify this directive, operations on the record area associated with a file are only possible while the file is open.
HOSTFD does not affect EXTERNAL or SORT files. Nor does it affect files defined in a SAME RECORD AREA clause in the I-O CONTROL
paragraph.
Access to the record area before an OPEN or after a CLOSE may result in a COBRT203 or a COBRT114 error, indicating that the
memory has not been or is no longer allocated for the record area.
Specify NOHOSTFD if you need to access a file's record area after a FILE CLOSE has been performed on it.
