This routine closes the file associated with the file descriptor FD, resets the file descriptor and removes the association with the ADAM parameter. It does not cancel the ADAM parameter though. This allows the value of the ADAM parameter to be reused.

CALL FIO_ANNUL( FD, STATUS )

FD = INTEGER (Given)

STATUS = INTEGER (Given and Returned)

• If STATUS is not SAI__OK on input, then the routine will still attempt to execute, but will return with STATUS set to the import value.
