		  = 1 for delete, = 0 for not delete
                  [3]  spare

     FILEID  ...  FILES-11 File Identification associated with entry.
     DEVICE  ...  Device Identification associated with entry.
     BDADDR[4] .. Address limits of virtual memory allocated to bulk data
                  [2] + [3] only used for internal data conversion
     KAUX[4] ...  first element,

		     (BFDEF,ADEF,PDEF)
     CATALOG ...  [0] = I, T, F for image, table or fit file
		  [1] = Y(es) or N(o), if FCT entry should be also recorded in 
                  relevant catalog
     ACCESS  ...  I for read-only, O for write or X for scratch file 
     FZP     ...  pointer to FCB of this frame
